The Chosen Ones

The english isn't the problem, most bugs you've posted are already known .

I'm having a problem at chapter 2 elite boss, when i use teleport strike, it looks like fradz likes to keep hiting the near lighting balls/orbs, most of the attacks are spent on them, and fradz is vunerable in this skill, so i'm pretty much dying or spending useless time and mana with this skill. With another words, the skills is worse than useless on this boss...
By the way, this elite boss is F*CKING hard now, i'm not doing any damage at all. But i'm not complaining, i'll go for the challenge .

Edit: Oh yeah, the above is true, but the principal reason of the weird behavior of teleport strike is this:
The skill teleport strike is a skill based on the damage, in another words, the hits of the skill are not that different from normal attacks(you can critical hit, use siphon life, etc), in another words, it's perfect for my fradz. BUT this elite boss that i refuse to remember the name(Noc'toriah ) have interesting debuffs that disable attack or skills for some time, almost completing each others(with a little gap between the debuffs). If the skills are disabled then teleport strike is unusable, BUT if the attack is disabled even if the skills can be used, it's useless, cause fradz has NO attack.
I was thinking it was weird that fradz kept hiting the lighting orb with the skill and it was not dying at all. Well, that's the reason(probably), if i'm wrong i would like to someone to explain me what happened so...
