Theres no way, alot of the high lvl players i follow play tank like (Zbra,Flats,Emongg,Samito…etc) and ive only ever heard they say tanks are really strong.
And again, i play alot of tank, i flex alot, i can see how alot of the time a game is won because of tank-diff, way more than the other roles.
Not true imo, support is the second most influential per player, they might be the most influential as a role but thats much harder to get to since its between 2 players, but as a player they are not.
The way i see it, tanks (the OP ones) are about 35% of ur team, both Dps are 15% each and both supps are 17.5% each putting the overral role strenght at 35 (supp) 35 (tank) 30 (Dps) and thats pretty obvious considering tanks counter DPS but help Support the most.
IMO Tanks (the op ones) are as good as both of ur supports in one player, let that sink in.
Ofc it varies from composition/map and all of that but thats the average statistics i have in mind.
(It might also be 40 (tank), 14/14 (dps), 16/16 (supp) on ladder btw because of the random solo q nature of the game, favoring the solo oriented role the most, wich counters DPS and buffs supp, also cuz ur Solo tank can throw the hardest by not picking the OP ones)
The right one imo should be closer to 32 (tank) 17/17 (dps) 17/17 (supp) , achievable by nerfing the OP tanks/dps (while buffing some of the bad ones) and buffing the support’s survivability while nerfing some other part of their kit i think.
That would make Tanks the weakest role but it cant possibly be good for any game having ONE player be better (by alot) than 2 of its peers, not possible.
And its like by ~1%, they would have the same impact as the DPS role has right now wich is still a healthy amount.
Edit: Quick maffs.
