With the new experimental card I think at least trying it is worth a shot.
1,3,2 fixes a lot of issues that 2,2,2 has but creates even more (projected barrier not being skillful, hog just isnt a main tank, no tank synergy, quick play chaos, tank queue times, etc)
2,2,2 still has the overwatch deathball feel to it where you group up and play as a team instead of quick play chaos
I believe 2,3,2 could be the best of both worlds. Some benefits being, keeping tank synergy (aka rein zarya), dps queue times, not ruining tank balance, raising the skill cap of support heroes, shield break is easier, less reliant on independant dps doing their job, leavers have less significant impact on the game, etc
Some negatives being, devs needing to optimize servers for 7v7, worsens the “why is there so much stuff on my screen”, overtime chaos/stalling, respawns most likely need to be slightly longer, AoE abilities could need nerfs, each player has less impact on the game (good and bad imo), small global queue time increase, supports potentially need to be buffed to deal with the extra player, etc
I believe 2,3,2 could be the best thing thats happened to the game since ironclad was nerfed and the positives far outweigh the negatives. 7v7 has worked before (glitched lobbys) so its not impossible. “If” a dev sees this at least bring it up for discussion please and thanks.
On a less serious note, 3 damage medals, 3 dps on a team, kinda makes sense… and also I really dont want to lose that teamplay aspect that comes from tank synergy, to me at least its one of the things that makes overwatch, well, overwatch.
