Lightning Warp does not target Ball Lightning balls

As title says.

This makes the skill almost unplayable especially in boss fights. It seems like the skill always tries to target a mob/boss instead of an eligible target like cullable mob OR Ball Lightning. The larger the boss the more unplayable it gets.

To clarify: You can target the Ball Lightning away from mobs, then use Lightning Warp to target those balls. As long as there are mobs AND balls Lightning warp tries to target the mobs (and debuff them?). If the Arena is too small or the boss too big you can't use the skill at all.

Please fix this.
