Yo,
Power-ups aren't necessarily a bad idea.
However, you need to delay them.
If you just allow people to run away to get power ups at the start of the round, they pwn you because they have enough luck to be closer to one than you.
At least, give them 30sec to spawn. Even 15sec would be nice.
Oh yeah, do the same for the perks. Getting OS by a catapult before the fight even began without being able to dodge it isn't really fun.
Thanks.
