Same I only have 19 ecs, and I am not sure what to get.
All the event items all have their special features.
Ion Carbine - Has 2 shooting modes and 1 melee mode
Flamethrower/Ion Pulse Cannon/Electric Staff - Fast firerate, great for pk but dunno which one to choose. Flame faster, but ion cannon has 2 modes, but elec staff is cheaper.
Heal staff/Katana - Staff heals you *wow* and katana is really fast.
Rely on chance and team, won 3 chances and the rest team.
The 2nd mode for carbine is sooo bad.
Flame is better than ion cannon
