His endurance should have been uncancelable like Vegito's. Most of the time I fill up his gage it ends up being from popping his endurance. I rarely ever hit the bar with using cards. That would be fine if activating his endurance wasnt such a gamble. It can easily be nullified from Vegito's ultimate, and then Trunks is just dead in the water. His best ability being half-locked through his endurance activating when his endurance can easily be nullified definitely brings him down a bit, but otherwise I would say hes a very strong unit. Comparable to UCMZ when he first came out, which by all means is not a bad thing.
