I completely and unequivocally disagree with Revanchist and Donovan in their interpretation that Easy is an acceptable difficulty.
1) At the point at which a character has Mastery in Battle Meditation, they have at least Force Rating 2 (by requirement) and 100 XP spent in Battle Meditation (assuming only the line to get to Mastery + Control). They likely have Force Rating 3+ and a whole mess of other powers and such. This character has several hundred XP and is extremely powerful.
2) The character's allies (or troops, in the case of e.g. Palpatine) are not going to be slouches either. Even Minion Stormtroopers have Willpower 3 (less 1 because DS use of Battle Meditation - more on that in a moment).
3) The power really ought to be more effective than the radio. "Tie Squadron 1, you are ordered to break off your attack on that freighter and attack the star cruiser." And that's what they'd do, because they're military and they follow orders. And if they were having second thoughts, they'd essentially be Coerced (a skill that probably works well over the radio in these circumstances).
4) -1 Willpower makes no sense . Like so much of this power, it is completely unreasonable and does not match what we see in the movies or the Extended Universe . If the penalty were "-1 Willpower to resist your Social Skills and Force Power effects", I could see that. But Stormtroopers are not less capable when under the effect of Battle Meditation - they are more capable. That's rather the whole point. They are not less scary (loss to Coercion), more likely to disobey or flee from battle (loss to Discipline), or more likely to fall asleep at their post and more sluggish in combat (loss to Vigilance).
It makes no sense . Can we agree that it is broken and needs to be fixed ? I believe the author wrote the power from the point of view of a light side character, and while that's fine for what it is, it completely disregards how the power is shown in many sources and the fact that it was used quite effectively by Dark Siders such as Palpatine.
1. So?
2. They're not necessarily going to be high-stat characters. Also, so what if they were? Is it unreasonable to assume a high-will character will have a harder time being mind controlled? Mind control is a HUGE deal from a balance stand-point.
3. I'm not sure what point you're trying to make here, that issuing regular orders works better than mind-controlling? Well obviously. (Although not in all situations) Dark siders don't have to do the whole mind control thing, they can issue orders as normally and still gain the benefits of the core power.
4. I totally agree with the "-1 Willpower to resist your Social Skills and Force Power effects" idea, though I don't think it's fatally flawed as it is. Although, even that doesn't fix your issue with them being more easily Coerced. Honestly, as a GM, I wouldn't allow a mind-controlled NPC to be coerced out of their orders anyway. That's the point, they're mind-controlled, their orders take priority over threat to their livelihood.
1. This should be a very powerful ability, since it comes at great cost and is only available after considerable time and effort. It will not easily be "overpowered" as so many seem to think, because the opposition should be equally powerful. If you've invested enough in it early on to make it seem "overpowered", then you're playing a one-trick-pony and the GM should be able to remind you of that very quickly.
2. What is this Mind Control that you keep speaking of? I have read the power many times, and if you mean, "If you fail this easy discipline check you're mind-controlled," then I'm saying that's a hilarious interpretation. It practically ensures that the so-called "mind control" will always fail . Also, it only works on allies .
3. The point I am making is that in its current form this power is less capable than giving your orders via radio. It is laughable, pathetic, and not worth the points .
In all seriousness, a lot of people in this thread seem to think this is a terribly powerful ability, easily abused and unabalancing. I don't get it. The power only works on allies. You won't be mind controlling them to run off a cliff, or you'll run out of allies.
I have read and reread this power in it's entirety, and feel that I have a good grasp on what it can and cannot do. I feel that a lot of people are making arguments based on what they believe it is intended to do, and that'd be fine, except the rules as written do not line up with those beliefs.
The reason this power is powerful is because it can grant a large number of Advantages to a group of people (and for a long time if you can activate the Duration upgrade).
It is not powerful because you can tell people what to do, or force them to do it. That is a completely negligible and unlikely side effect.
What? You literally can force other characters to do what you command them to do. That's what the dark side mastery does. In what universe is forcing another player's character to do what you want them to do not a powerful ability.
Imagine a party comes across an NPC that has a talisman of the iron fist that's been an heirloom to their family.
Player A: Ok, I'm going to try and roll Negotiation to convince the NPC to sell us his talisman.
Player B: No, that's stupid, let's just kill him.
Player A: What? No way! You might have a 16 Morality but I'm still a paragon of light!
Player B: Well, I have this Battle Meditation power, I'm going to roll that. *rolls dark side* Ok, now with an Easy Leadership check... succeeded! Ok, now Player A, kill the NPC.
Player A: Um, no, I'm not going to do it.
GM: Player B has the Mastery power, you need to make an Easy Discipline check to resist.
Player A: Ok, well that's not so bad...
Player B: Don't forget, your Willpower is considered to be one lower!
Player A: Really regretting not raising my Willpower now.... *rolls* Oh you have to be kidding me, six Advantage! Is there anything I can spend this on?
GM: Uprgade your attack against the NPC?
Player B: Kill him. Kill him now.
