I know you all don't want to be stuck reading a long, drawn out forum post so i'll get straight to the point.
I held a 3v3 earlier on trappers atoll and numerous things were wrong with it, direct quote from other forum post:
Spawns. The spawns are too random and TA is a huge map. if everyone spawned on the north end every time during that, it wouldnt have been so bad. teams were scrambling to regroup and fight over and over.
Rules. I admit, this was poorly thrown together, it was just meant to be a test to see how things would go. There needs to be more rules such as you have 40 sec to get back past boundary or 1 point deducted, no passing boundary or 1 deducted etc etc and they need to be watched closely
I liked each team having a seperate scorekeep. that worked quite well but one supreme ref wouldve been good too.
Too many spectators. about 10+ people were there watching everyone and they got in the way and trolled etc
The biggest thing was the sheer size of the map and the spawns, if that was made different somehow, it would've been a lot cleaner. I really think that HCS should put in private pvp lobbies that DO NOT give XP, or valor. so people could have 3v3s, 2v2s, 4v4s, 5v5s, etc. all at their own liberty, creating their own teams.
Anyway, it was overall a really fun experience, and I hope that in the near future we can do a more cleaner version of it again.
In short: I think HCS should add private lobbies for people to host their own events and such, trappers is just too big for certain things.
