I think the balance is quite good mostly but jedi rely way too much on push 3, and not having it is kind of like a challenge mode these days against anything that can't aim decently. Coming from a person who mainly plays with medium speed stances.
Wookiees aren't that hard to deal with. It's mostly a mind battle and predicting when the wookiee will charge. It's quite easy to dodge if you can expect it.
Edit: After having my FP reduced from 100 to 0 in 4 seconds from droideka fire that glances me I'm calling bs on deka vs jedi balance.
