The thing is well and bubble have counters. You just wont be able to use those. Because if this wonderfull idea called "super tiers" Where a bubble or a well will always be the first supers to get. Because its definitely fair and well balanced :)

Bubble has arguably more counters than before. Shotgun, Barricade, any super, Conditional, any sort of freeze, cerberus, witherhoard, snipers (Though this is a tricky one), any none lmg heavy. If you have a coordinated team also add primaries since with coordination you can destroy the bubble with ease.

Yeah, but when it is completely expected that you should not be frozen and still are, that isn't a counter, its unintended behavior, and a bug.
