by definition bap has more burst, i was just refuting your point.
you are still forgetting that we are talking about pre dps passive, just a single flex support like kiri or ana could keep a team from exploding, infact when i was playing support during those seasons, id have my ana’s or kiri’s solo heal while i fragged on bap and bullied their dps, guess what, i got to GM with like a 60% winrate which is higher than my genji winrate ever was.
No, survivability matters so much more, especially on support.
burst doesnt mean crap if you cant burst through the insane amount of heals, i literally have clips of me hitting 500-600 damage on a squishy being healed by a single support within the span of 3-5 seconds.
if you are alive long enough to capitalise on mistakes that is infinitely more valuable than burst.
