Well...
It`s true that currently many of PvE aspects is designed around tonns of damage from modern DPS chars.
But simply being true don`t mean that it`s alright. I think that in that terms all the major OP DPS trio needs a nerf - MSB, Canna, Chungha. And a comparable buff to old underpowered DPS. My opinion only. But...
Every serious balance change is a double-edge blade. Especially nerfs, as basically everyone who use this char will QQ and vote against it. More changes- more QQ.
AGE staff is somewhat right in what they say about balance changes. It`s either "we have a fully re-balanced stuff" (A LOT of work, theorycraft, and customization. More customization => More possible bugs or glitches. That`s good if you`re IMC who have a full server&engine sources, and can live on selling contracts, but for small private server staff...? Full balance of the whole game can take years.) or " We`re going for vanilla KGE balance changes" (Still a good amount of work, as sometimes there`re changes above simple numbers. Like KGE dagger user reworks But at least it`s "you know what to expect", and due to having a huge delay- ppl can prepare for incoming changes.). Going mid-way can provoke both OP char users (who`ll QQ due to their chars being nerfed) and causual players (who`ll spam 100500 posts to buff\nerf chars they love or hate). I think it`s wise for AGE to NOT touch balance until it`s a critical serious problems. Just to avoid ppl rushing for a huge changes. red20ro is right, there`re already a lot of changes announced & coming, that`ll affect whole server population, instead of bringing balance-related drama to small groups.
As for RCaisse PvP...I`m not into PVP, actually, just mentioning.There was ppl who compared R.Caisse with Merc.Calyce. But there`re actually a big difference there right now. Thing is even tho Merc.Calyce is powerful (actually not SO powerful after all the nerfs), right after she went OP in CB there was a direct counter-pick introduced, being Moon with his Cancer buff (still LUL on this debuff name, even tho i have cancer IRL...).
R.Caisse is hardly countered by anything due to perfect stat combination- ATK + IDEF, allowing him to counter block-focused fighters like Ania.
