The Falcon is half your list, if you load it up to be useful. Taking it limits your overall firepower in total, in exchange for being able to cover more of the board, with again a single ship's firing arc. Sure it's 'easier' in that regard but you're paying for that ease. If you're up against one there's all sorts of things you can do to deal with it. Asteroids stop it from firing, and it's larger base makes them harder to avoid; learn to how set up, both the asteroids and your initial deployment to force them to come into play. Get close, and keep shooting. It's going to get get 4 dice, against one of your ships. How many extra dice are you going to be rolling against it, and it's still only one agility. Things like C-3P0 mitigate this to some extent, but roll enough hits and those shields and hull melt away. Want to corral it's movement? Get an ion token on it. Suddenly, with how far they move with even a 1 forward, the 1 agility YT doesn't just want to avoid rocks, it doesn't want to be facing the wrong direction when that second Ion token falls. And your rocket launcher analogy doesn't really pan out. I don't remember the rocket launchers in UT or the soldier in TF2 being boring instant win buttons you seem to think the YT is. And no, the AWP in Counter Strike isn't either, if it were I wouldn't be absolutely terrible with it...
I don't believe I said anything about turrets being unbeatable. I've flown against them plenty, and won against them plenty.
My post wasn't asking for ways to beat them, or claiming that they are "overpowered."
Just that they nullify the need to get your enemy inside your firing arc, and that takes away a pretty important (and fun) aspect of XWM for me.
So I don't fly them.
And the rocket launcher was an example. I'm not going to compare a bunch of video games in which RL's are "instant wins," There are plenty of games where one weapon is extremely powerful, and takes quite a bit less skill than the others. I could throw out examples or analogies till my fingers bled, and you could disagree with me all you want, but that's not the point.
