Let's hope Rangers don't get literally get nerfed to the ground. No, I'm not one of those cancers. I only use 1 Ranger in PvP as I'm already contented reaching 4.4k as anything higher gets more 3-4 Ranger cancer teams. While they're seriously OP while stacked together, we seriously don't need another Valiant Force "Mage-tier" class if you know what I mean
Nerfing will always be the last solution after weeks of balance testing. QA team hates nerfing as well
There is no need to nerf. I always believe Ranger's aura is to compensate single targeted skill unlike mystic that has aoe skill and healer that has heal skill. The trigger aura helps ranger to be able to do something before getting killed but that's only valid in pve where enemies have extremely high health not pvp where most heroes will have around 10-15k health while critical dmg is 4k-5k in avg.
I believe restrict the number of trigger per turn in pvp is the best solution without having to nerf trigger rate or critical dmg.
Limiting only 1 class per pvp match is widely suggested by many players but it has its downside as many low lv players do not have all class yet. Don't forget that RNG is preventing them from having variety in arena team (some has no 5* shadow, champion or ranger etc till high lv) in the first or second month of their play time. Many that vote for this choice are players above lv 70 that are already at confortable zone with class variety but doing so will ruin new players even more. Do not forget a lot of complains regarding arena matching even at 1100 pts.
