Me and some guildies used this spell to clear the crumudgeon fighter camp. Its impossible to pull just one mob from the camp, usually 3 or more come. I would cast vines on one of the additional mobs to lock them down while we killed the others. Kinda like mez..but vines doesnt have anykind of spell effect to show which mob it is being casted on...which sux cuz my team cant tell which one I'm freezing and they sometimes break the vines and the mob comes after me. Two things need to be done to improve this spell:
1) improve the range or casting time slightly
2) give it a spell effect so people can see which mob is effected
