However, Bastion with Reinhardt is near unstoppable, however he can at least be stopped with a well played genji counter, where as Mei on the other hand may be harder to play for noobies, but a compitent mei can actually "be" unstoppable.
Mei is the most broken char period, on account she can literally wall off areas of the map unlike anyone else in the game, and unlike Macree's stun, her freeze is "alot" worse.
Her Q literally dominates the enemy team because it actually cannot be countered if triggered right except for maybe a genji/tracer moving "Just" in time.
And her self heal immunity is even "more" broken as shit than Bastions, with its surpisingly short CD and the ability to prematurley break it to move away and continue fighting.
Bastion is hard to counter but not impossible, but Mei, a compitent Mei player is "literally" impossible, with a good mix of range (rmb) and melee (lmb) attacks.
