After completing and exploring Act 6.3 I'm going back and working on 6.2 after finally getting a few pivotal champs so that it's not a complete nightmare (5* Sym Supreme, 6* Heimdall). As I've worked my way through 6.2.1 - 6.2.5 I've noticed one thing... CHAMPION GATES SUCK!!!!!!! I have a pretty large roster of 5 and 6* champs with a decent amount of game skill to go with those champs, but I'm finding I'm struglling ALOT on ALOT of paths. I didn't find 6.3 anywhere near as hard, and I'm just wondering if anyone else who's explored 6.1,6.2 and 6.3 feel the same way.
Also having to face each quest boss 10 times is way too much... 6.3 got it right having only 6 paths even if some of them are longer.
The thought of having to deal with whatever gated path nodes are leading up to the next 9 6.2.6 Champion fights makes me really want to consider not exploring all of Act 6
