This was an awesome event and all, but if you're holding another fight-to-death the rules should be overlooked at.
"Surviving players will win a prize".
This eliminates the feeling as to win as a team because it's all about surviving as an individual, not winning as a team.
So tactics, organization etc has no part whatsoever, as long as you are at the back whacking that mana pot button.
But if you insist on keeping survival-mode on, atleast make it smaller teams such as teams of 2 or 3 vs others who are teamed up the same way.
Or just a free-for-all slaughter XD.
just my thoughts~
