Hi
Life scrolls should have some kind of time limit during wars.
The wars look like this: no matter how many people defend the flag, a few mages under the flag spam life scrolls and use their aoe skill to destroy the flag and people can't do anything to them right after picking up their character.
This tactic shows that the war is won only with money and not with guild coordination or an organized attack.
A short while after using the life scroll, the enemy character cannot be seen and he can now use skills on his device. It is also impossible to block such a character with other skills that are already in use, such as circle from warlock.
My proposal is to have the life scroll have a larger cooldown during the war, or to completely block the use of this item during the war, just as adding or removing people during such events is blocked.
