Generally I like the idea with the champions, but... Here some notices free from my mind:
Ran several EH quests yesterday. Seems every 3rd mob now has Champion. Palace of Stone - a mob of 15 animated rocks, and 5 of them Champion?! EH hits on my melee tank were ok, just about 100-200 dmg from the champs - far away from the reported 1000 dmg oneshotting all but the best HP builds. This at about 200 PRR and about 150 AC.
I just happened to kill about total 200-250 champions w/o getting one single chest. I know, this is random, but - WAI?!
On EH wading thru legions of champions still was no big deal. Just some inflation of HP and I emptied my mana pool somewhat faster. Only thing stinking me big time has been the fact that both mobs and champions increased big time in both power and quantity on EH when adding more party members. This also holds true for the one EE quest I tested (lots of champions in The Snitch too) and the HE quests I ran yesterday after the servers went back up. Not funny to get a big time scaling on champion quantities and powers with MORE members - I always thought the champions were supposed to increase group play but currently even deter me further from picking up group members, except for selected players I know that know their trades.
My suggestions to the Devs:
1.) Finetune the ammount of champions. Running quests with about 1/3rd of mobs (!) being champions is just plain ridiculous. 1/10th or 1/8th of total mobs sounds about right. Even better would be a mechanic where different mob types have different chances to spawn champions. But this certainly would be too expensive to code, I suppose. Sometimes the champion mechanic is lacking reason. Animated Rocks spawn Champions?
2.) Tune up the chest droprates. I expect getting some reward for killing legions of champions. At least make them champions drop guild renown. I do not expect a chest for each and every champion. But about 250 of them and no chest?
3.) Tune down scaling for champions. We are supposed to fear them on soloing, but we should be able to break thru their ranks on large groups.
