Support main here. Supports are crazy overpowered and have been since release. It is disproportionately stronger than the other two roles which is why you can justify running comps with 0 dps in exchange for more supports.
Instead of bringing others down to the level of the worse supports, the dev team have made it a habit of buffing the other supports up to the level of whoever is busted at the time (with some exceptions of course). They have slowly been power creeped over the games duration and it is wild.
Like I obviously don’t mind it too much since it makes me a heck of a lot stronger in comp. but acting like it doesn’t exist is a little silly.
