For a total time of approximately two months, the playerbase will collectively have access to a pvm buff. The buff itself doesn't reliably trivialize anything, but the consequences in a group setting are potentially pretty bad if it can prevent the group from gaining kc. While the post doesn't say, the original mahjarrat aura effect did this and it's quite possible this buff would reuse that code without much thought to change it.
Some of the consequences are:
Players with low kc already struggle to find raid teams. This is almost two months of essentially needing to get lucky in order to gain any kc so strangers know they have at least some basic experience with the fights.
Players with a high kc look to keep increasing it. There are numerous people in the thousands who raid often and push up their kc further. This is almost two months of stalled progress on that.
I don't see a world in which this is not completely anonymous, or maybe announcing to the group at the end of the kill when some damage is already done. Letting people anonymously troll groups, knowingly or not, is pretty clearly a bad idea. Even without anonymity, better to prevent the salt in the first place.
Some people don't care about kc. Some people do. Cue pointless arguments over the course of two months that could be easily prevented.
It makes sense to disable timers and whatnot based on a limited time buff, but ordinary kc should be left intact for the teammates of the buff user, whether or not the buff user themself gains kc. If that's already how it's going to work, then great. If not, please change it in the meantime.
Edit: Changed the wording a bit to clarify that the relevant duration here is how long the playerbase has access to the buff, not one individual player.
