Omgf, you are right, and I always thought it was position bug, very noobish of me :lol:
Back in topic, a warlock without his stun abilities would be a useless class, and fear doesnt ever work for 5 sec, enemies wake up earlier due to dmg taken.
Ok high amped warlocks are op because they can kill you in one stun+dark circle time, but thats the exception, not the rule.
And priest are one of the classes with the highest chance to kill a warlock, just stay shielded, use armistice to recover and word power to drain their mana, takes just one power word to empty their mp bar and at that point you have a dead warlock.
