I guess we can start a list of events that we can think of and have someone willing to work and make it.
So I had the idea of capture the flag. Instead of blocks it would be animals. You would lead each animal through the battlefield -or away from the main action- and you would have to guide them through the frenzy. Each team has 3 "lives" so whoever has 3 of the enemy teams mob wins.
Second, paintball,maybe we could have a paintball plugin that uses snowballs and towns from each pokemon region as like a battleground.
(I got this idea from another server but its pretty fun. :P) Anyways each map would be a battleground for players to use. Maybe like random events such as, Trainers Vs Gym leaders or Everyone vs Elite. or something whacky like that.
I am out of ideas at this time so maybe you peepoles can talk about an "awesome" Event idea.
