Zalohi got multiple ideas.
Uberkreig (optimized for mvm)
25% faster uber rate
Dose Uber and Kritz at the same time when uber popped.
Auto-Gunshot_Bride (Made for frag vids)
Automatically airshots people in the air if hit with rocket when jumped at same time
No Random Crits
50% less damage
No Rocket Jump
Roamers Boots (Optimized For Comp)
100% damage ristance against own rockets
25% faster movement speed
just to add to this, I would add a scout gun that where you press one button and it kills everyone on the other team
