I don't have Wicket nor Logray so I'll go with what I have...
Teebo (L): removes TM and gives Stealh + TM to others
Paploo: gains taunt for 2 trun when using his ability and when he gets stealth from Teebo. Get heal (+ protect with Z) when he get a buff or debuff so, hopefully, he'll always be taunting and getting H/P back.
Elder: cleans and keeps others alive and fast (TM on basic)
Chirpa: Buff, Assist
Scout: Damage and assist
Not the best possible Ewok squad but the best I can do with what I have...
I doubt I'll have time to gear them up sufficiently (all G9 only atm) so let's wait and see. I hope we won't get too much AoE attacks from the enemies, whoever they are...
