35% chance to assist on a team where B1 assists every time anyone on the team takes an action turns into nearly 60% chance of assisting every time one of your guys takes an action, which is fairly significant. It could get even more significant if you stuck Droideka on a Geo squad under Brood Alpha instead of Poggle...
Given that Droideka's damage immunity can be dispelled, I'm not sure that it'll reliably get a turn without that TM boost. With that said, I can't disagree with the idea that you should be able to choose a level you want an ability to function at if you've maxed out the ability. That would serve to address any and all possible future occurrences of "this ability is better before leveling!" type issues.
Math for chance to assist: 35% chance to assist means 65% chance to fail to assist. Triggered twice, with failures on both, is a 65% * 65%, which has a 42.25% occurrence.
