I just found a great new dive strategy. So basicaly u need baptise, lucio (replacable), genji, tracer, rein, monky. The point of this strategy is to charge in with rein, protect him with winston bubble or immortality field to save him. And ofc use other heroes to support the dive. Tried it on comp and worked 3/4 times. 
thats a great way to get rein to feed
Thats a really bad comp. You can just use Zarya instead of monkey and just have one flanker like tracer.
Also no balls charging with rein is terrible in any situation
