It doesn't make sense when on server where you have buffs from NPC and have mp pots cancel rate is 100% and it's removing 5 buffs.. This is totally disbalance because when you are in party you dont need a buffer, sws, bd, so when enemy party comes with 3 or more sps they cancel all your buffs and you have no chance against them because your party is based just on dps without bd sws and etc. So sps's just cancel all your buffs and you can't do anything. On server like this it's normal when cancel take out 1-3 buffs randomly.
