“Zerstörungswut” (look it up yourself :-)) is what happened to my Warlock after I decided to respec him to 0/21/40 Destruction last week. I love it. I need to replace most of his gear (started to), but seeing those 6k+ Shadowbolts pop up on your screen is beeeeeeeawtifull. Especially when soloing and Backlash triggers, and the Bolts crit, oh lordy. Double-BAM in your face. 🙂
The Warlock is fun again. I got so bored with Affliction and was towards the bottom of the damage meters anyway, so I thought “why the hell not” and did it.
I like spamming critting Shadowbolts. Its like zoning out after tanking and healing an instance. I recommend that anyone who has a tank or healing character level and gear a DPS class. Keeps you mentally balanced. 🙂
