sry for the spam post but you should use antilag and effect limitation, your lag in game is quite constant.
And about the elf soldier, it was made not to be able to be used from characters level 400 as far as i remember now it says "you can now stand alone without my support", which means it is used only by characters that level up so i dont see anything bad in it? If it doesnt say this, then it was probably because of the host change and it can be fixed.
What we need is to change the level of its availability. Example, if you're level 300 already then the soldier's buff should be disabled. I remember when the host is on US it's like that. Well yea it'll overall ruin PvP since you can get free buff although it's not that strong. Let's just wait for their response.
This was somekind of granted already months ago - level which you can get buff is up to 300 and if you go over 300 you can't get buff from Elf Soldier.
