Buffs that brutes need:
- immune to any form of stun
- slight hp increase
- explosive resistance (probably like 20%)
- ability to attack when your club is gone
- reduces bullet damage by 10% (excluding headshots)
This might seem excessive, but the main issue is that brutes die way too fast now.
Once you throw your club, you're as good as dead since you're really slow and big which makes you an easy target.
