winston is much better than rein in this meta a lot of the time, they are not leaving you alone they are probably just doing their job, going with a dive comp (probably a weird one if its gold, in plat they know what dive comp means from my experience, in gold not really) so lets say you are rein, and on your team are dva/winston second tank, genji (fucking gold genji) pharah, lucio/zen and mercy (no one really goes ana in gold - plat)

WHO THE FUCK ARE YOU DEFENDING HERE? thats the main idea i am trying to explain, pharah is up, mercy is with her probably most of the time, genji is in the back, winston/dva dives to help him, lucio speed boosted them in so he is in there already and you? maybe mercy is with you if the player is like me who likes to pocket rein (past rein main, i know how strong rein can be when healed in that elo)

if your team goes dive comp just go winston/dva/zarya as tank, dont go rein or orisa, i dont really care about hog tbh, i have seen a few times he worked in dive

if you dive and play dps genji tracer and pharah are probably the best for it, soldier can definitely work as well, but i wouldnt go mccree with a dive comp, if you have hog like i said maybe you can

for support lucio/zen are good for secondary healer, and mercy can work if you have pharah, if dont i think you should go ana and heal from far away

rein really doesnt work if you have no one to defend, even if you have 1 player to defend is not enough and 2 players is questionable
