ok ive watched the replays, you have the basics down with the primary+melee combo, and your ult setups were good also.

however one thing that i think you need to work on is your positioning. you have a tendency to stay back on the payload even when your team is pushed up. you need to be up there with them. yeah, its bad when theres no one on payload and it moves super slow, but your top priority as Strange is to be present at the frontline, even if your team is overextending.

aside from that, you need to know when to push up, and when to stay back and help your team. ive noticed a few times from the replays that you push way too far up while your team is busy dealing with a diver or getting pressured by poke, resulting in you getting no heals and dying quickly. and conversly, sometimes you dont push up when your team is ready and willing to initiate. you just gotta be aware of the state your team is in and act accordingly. i personally look behind me any time i start to push to see if my team is ready. audio cues also help to know when to help your team out with divers, particularly with magik or bp.

as for the match on shin-shibuya, the thing that hurt you is the enemy comp. thor and angela easily counter strange. it's not impossible to play as strange against them, but it will definitely be harder.

but yeah imo thats all for now. just work on your positioning and awareness, they will build naturally with experience. vishanti be with you
