I’m not sure why everyone is dancing around the real issue, which is a few OP heroes ruining the game.
Min/maxing? It’s only possible because of a handful of super powerful heroes. Almost every min/maxer team uses Panzer and/or Dogface as DPS. Doesn’t that tell you something? When I see a team of all 4-7* silver/golds and a 10* Matador they get absolutely trashed with a “normal” team. I never have issues with min/max teams using other DPS like Maven, Clyde, Hecklar, etc. The couple of super powerful healers/support (Heimlock, Mandrake, Caine, Nightingale, Ifrit/Flatlin) just add to the problem.
I know no one wants to nerf heroes and would rather buff all the others, but if it’s done carefully it would just make the game better as a whole. Give Panzer 14 shots in her shotgun. Maybe reduce the damage on Breach and Clear slightly. Tighten up her shotgun spread to help compensate. Suddenly she is still a great burst DPS, but can’t be run at 10* silver and decimate 3 heroes within 15 seconds when you min/max with her. She also can’t be the ONLY DPS in the current Ifrit/Flatline meta.
Next look at Dogface. Instead of allowing him to do insane burst when his silver and bronze pop, maybe lower the damage on them, or further reduce his clip size to 16. Again, this will keep him from being used in min/maxing teams where his 2 skills pop and he kills half a team of weaker opponents. To compensate slightly reduce the shields on Caine, Showtime on Ifrit, and maybe the healing on Heimlock and Nightingale.
Also buff all the crappy DPS in the game. Give Maven some sort of burst, and increase her health. If not make Vampirice Cloud do something else like have a chance to stun a few if it gets a tick off. As is it’s too easy to dodge Vampirice Cloud and Hallucinate and Maven has no burst damage. Miasma is random and her health is low making her a poor DPS choice in PVP. The same with Clyde, his hp means he dies nearly instantly and his skills are too luck reliant. Most of the DPS just need hp boosts and a little better burst damage and they would be great.
Of course on top of stopping the min/max problem, this would also solve the current heal meta. If Panzer and Dog are weaker they don’t kill energy heroes as fast. Combined with more hp, heroes like Heckler or Sapphyr could actually stay alive long enough to have a chance to kill Mandrake and Ifrit. You could run 2-3 DPS teams and they would have a chance to kill all healing teams +Panzer.
Then just add in the changes already mentioned (no more skill points increasing power, PVP giving xp, etc.) and voila, PVP is fixed!
