Well, the only thing I have done is Dragonstar Arena. Sadly we didn't make it very far because my normal group is missing and the gear really sucks... However I did find a few bugs with how far I have gotten.
1) During phase 2, no idea what is causing it but we gotta move the next fire, for some reason and it may be lag, but I hae no idea, but all of my abilities are unable to be cast, not even ultimate, and a few seconds later i just die with nothing but a 600 dmg hit in the death recap.
2) The reds for the AoE's are disappearing, no idea what is causing it, but when I have a heal or 2 down, the reds just don't show up all the time, don't know if my healing effects and just cancelling them out or if they are causing them to disappear.
So far that is what I found along with a few bugs out of the already known.
Suggestion: I'm not saying change it now for test purposes, however my idea would be to give us like 10 rezzes then earn 2 for every wave you defeat. Obviously not definite numbers but use a system like that where you earn the rezzes instead of just having them given to you, i think that would be a pretty cool system.
