Dive will NEVER come back, until new heros will be reworked. All new heros just kill dive. Like brigitte with her stun, Ash with her dinamite that deals insane AoE. There is NO way dive will come back. There is just to many heros with CC.
Now everything is very slow, alot of CC, you dont really need a big aim, couse everything is so slow, you dont really need to oriantate on the map becouse of big amount of shields.
Back in the day everything was fast, u needed skill to kill, aim, where u jump on monkey, where u dash with genji, how u tp with tracer. Now u just go with double shield with 6 ppl, spam enemy shield and who ever breaks the shield first , wins. Another thing that matters nowadays is ults, who makes best ult that wins.
So winston , genji, dzenjata they just NEED, REQUIRE a buff.
