Well, my party just popped 1000xp earned (yes that is over a year of weekly 6 hour sessions). Still not seeing any major issues balance wise.
Yes the combat characters are really good at what they do (and have picked up secondary specs, like our assassin droid / mechanic). But so is the pilot/slicer and the scout/ninja and the talky character that can buy your speeder off you and then sell it back to you for a profit.
But it is all good and cinematic fun.
I suppose I am lucky in that my players have stopped going "up" and are going "wide" in their characters abilities.
If you have a doctor in your group, then try have him get pressure point and abuse it. That aside I agree that the system was created with the built in balance of the dice themselves being balanced to perfection. They just made defensive talents a bit too hard to get enough ranks of and a bit too expensive to use. Other than that, the game has a great balance, apart from the insane pressure point exploit.
Are you telling me you don't know how to deal with that problem? Try and do that to a storm trooper. who is shooting you from across the room. Or through a small shooting port. It is a freaking Brawl check. How many doctors do you think are going to be running around with a 5 brawn? And even if they do have that,... a storm trooper or whatever placed in an inaccessible location renders the power moot. A simple application of the Order 66 podcasts "The List" solves the problem,
have targets at long range.
Use Elevation.
Have things for skillful characters to do to effect the encounter.
You think the ability is broken. I think you have just been doing poor encounter design and allowing a one trick pony to run roughshod over you.
You should have some guys the medic can use pressure point on. But there should also be bad guys the medic can't deal with be it range, inaccessible location, etc.. There should be things that play to everyone's strengths and things to challenge them in their weaknesses. Things that would as a team will be easy to solve and things that allow the players to be bad ass. And some things that are difficult to deal with because no one has that problem in their wheel house.
All of these things don't need to be in every encounter. but they should all be considered for every encounter. And you should occasionally have encounters that just simply make the characters look really bad ass. Because that is part of the fun.
