As the title says, we need SEPARATE buffs/nerfs/balance tweaks for PVE and PVP. 2 completely different game modes with completely different strategies, objectives and player types need different tweaks to the game.
This has become especially evident in the cases of the extreme and repeated nerfs of the Managarmr, a new and versatile creature that quickly became as useful as throwing small feces at a wild Giga... All because of the outcry of a portion of PVP players, while completely ignoring, disregarding the PVE community. While PVP was focused on griefing fellow players with Manas, PVE players needed that versatility to focus on boss taming/killing. You can see the frustration on both sides. PVP is still and will be forever complaining about Manas, while PVE clings to being able to still play with that creature. This is only one example.
For two game modes you need two game settings. It is only logical, as a famous saying goes.
So please, for the sake of the PVE and PVP communities, revert those extreme tweaks and focus on implementing them completely different in PVE and PVP game modes. This might be the most urgent game balance.
PS: DO NOT, I repeat, DO NOT make this a discussion over PVE/PVP supremacy. If you want to know, they both suck equally bad for different reasons!
