The main problem is: many people think a ~50% loss in damage for a 25% gain in ACC is not a fair trade.
The best teams right now are the small teams, 3-4 member in a group. The loss of damage is felt in these small groups. Esp without a AoE blaster.
In the higher-end hazard zones, mobs with 2 bosses and 2 liet's and a few minions are common. A Illusionist is busy just holding on to the bosses. If the liet's/minion are not defeat, only option at this point is decieve for us.
