It seems to me that this event is not balanced at all, in the last match my team total damage per player was like 6k, 4k, 7k as per the other team was 33k, 30k, 20k. The matchmaking system shouldn't consider the atk attributes from the players to divide the team? I was going to say it would be balanced this way but the correct word is "fair". The fight wouldn't end in less than 10 seconds.
The difference was so big because one of sides got better buffs. 3v3 is all about getting lvl 3+ buff at the start.
The event is totally unbalanced...it just throw inside players at random. No levels, no gear, no XP, nothing at all is taken into account, it just throws people inside that probably signed close to each other.
