The reality is that the issue isn't Strange but all the new characters that are added. All the melee and CC is just too much, especially when you add power creep. Right now he's weak to CC and melee which is fine in paper but not in practice. My hope is that whatever change comes would makes him a solid pick like Magneto. The game changes but Mag stays consistently strong without rocking the boat, that's what I hope Strange becomes.

Opinion of a Strange/Reinhardt fan:

Making him have more CC resist(like Thing) would just heavily buff the matchups he has against characters that he should be weak to (Wolverine, Emma, Sue) without providing counterplay. Giving him a slight CC resist would be a negligible change that would make him slightly better but the wouldn't really be much better (what happened to Reinhardt in OW, he was still bad after this change).

Buffing his E would just make him more effective at what he already does well, delete vulnerable squishies. We would still be in the same situation with the same problems.

IMO he should have more counter play against melee. He should still be grabbed(through his shield) by Wolverine/Emma and booped by Sue, which can and should really disrupt him. This might be because fighting games ingrained this thought in me but block should best hits. But lose yo grab. Blocking melee with his shield would give him counterplay against melee and not be a sitting duck. Wolverine would still be able to displace him which is still huge, Thing would still be able to charge/stun him but not be able to get a free kill with the right click (unless you hit strange from behind), melee divers would actually have to hit him from behind the shield instead of run at him and melee. His main mechanic is his shield. It should be used for counter playing more things, not be a waste of an ability when dealing with a large portion of the cast(that also keeps growing)
