My Cleric

I personally think the best way to get aggro back is to spam heal / party heal / rejuvenate.. heal can draw aggros.. and it's a safer option than to try bash esp if they're dying fast... =D

(If you ever had to tank KQ boss, healing yourself, whether you need the heal or not, can keep aggro so well you'll surprise your KQ mates xD)

but that may depend on your playing style.. Some clerics -eye Helion- does better dmg, and can draw aggro quicker and better than others.. I guess that's where the experience comes into play~

You eyeballin' me girl???

My tip was for more of a duo situation, sometimes trio, with a mage. For example, I was with 2 mages doing the Caiman Giant, a boss in Swamp of Dawn. The mages were L98 and L91. I would attack first, then they would join in. As long as neither would have crit hits, I would keep agro. If the 98 drew agro, my heal went to him and we would still finish him off pretty quickly. If the 91 mage drew agro, it was 50/50 if he would be 1 hit and eat dirt. In that situation, me being a clank made more sense and resulted in faster kills with the mages free to bomb away without much worry. And yes, experience is a key factor in playing your part. I was happy to see that they nerfed the exp rewards in CC. I think way too many players leveled without really learning how to play the character that they had chosen, and it is showing up now in the upper levels of the game.
