Nothing too special here. Just my update for 3.5 on ally based Gwen. Some changes compared to previous iterations I saw on forums:
Bandit as default 2cc drop. It is so good.
Thunderstrike construct instead of Bobcat. Upping the cost of Gambit from 2 to 3cc hurt the combo a bit. Construct is a middle solution for
''hasted'' 2 damage. Advantage being it is unconditional for 5 cc. Disadvantage being it is less damage then Bobcat + Gambit, although if one sticks on board and you can chain them it is similar. It also helps to kill wisps and worms.
