I disagree. I am so greatful that the encounter requires planning and teamwork and that a group of 8 players can't just hack away for hours to kill a raid event boss. My feedback is well done making a boss encounter difficult enough to match the reward you recieve for killing it. Don't change a thing with wvent bosses and use this type of thinking going forward.Also I think that the bosses and/or troll adds are WAY too powerful for players of the appropriate level range. Not to mention the super short decreased spawn time of the adds.
I love the graphics. I can't wait for the issues with lag and chat to be fixed so some of my friends that are playing on iPod 4s can join in the amazing work you have put into this upgrade.
