I'm still a new player, approaching level 50.
My best squad consists of the standard units (Chewbacca, Luke, Talia, Jedi Cons., Royal Guard), currently around power 11000.
Enjoying the game so far as it slowly unfolds (I play for free, so far), I thought I was doing decently, employing a reasonable tactics (although I'm no mastermind, and I can't remember all of the combos and weaknesses of all units). At least I typically find the in-game power estimate reasonably accurate in predicting the outcome. I took this to be an indicator that I was doing OK, at least around average.
That was until I encountered the Kanan Jarrus + Chopper combo in the Arena. In battles against those, even when all my units are several levels higher than my opponent's, AND the game's power estimate is in my favour by more than 2000 points, I get wiped out entirely before I take out one of the opponent's team. They appear to be immortal, because they can interchange their taunts and protection, so all my firepower goes into armor that comes back the next round, especially when combined with Hera Syndulla, who always seems to manage to give Chopper back up plan just when my next shot would have taken him out.
Is this combo greatly overpowered, or am I overlooking some weakness it might have?
Or am i putting too much into the in-game power estimate?
Thanks for any advice.
