Hum ok can be explain like this, but i'm not sure. I ask to some friends to try on their rerol or main BM. Indeed, all got the same issue, inscrease of MS like +20/30 (in F12, depend to people and connection) (so it's more important on F8 and raid) compared to fire or lightning build.
So we can conclude it's not an individual problem. So the real question is : is it only on UE server ? bad patch application ? 3rd spé only opti to UE 4 (but KFM don't have this kind of problem so....). It's like NCSoft don't know about this problem.
I'm not sure that support know this problem and could help anymore...
If NCSoft could be read here will be really nice. Just know if it's normal or not.... (but it's not normal than we can't have a stable ms server with this 3rd spe).
I was really happy to tried this specialisation but now i don't want to play anymore my BM for this issue and cause fire is really to low compared.
So communication NCSoft please :o, don't let us without informations !
