PVP is the backbone for any game. SM2 needs rebalancing. Assaults AOE and melee with the hammer has too far of a range. Vanguard grapple hook CD needs to be faster and be able to hook Assault class. Tactical weapons needs to be fine tuned. Possibly need to be able to carry 2 main weapons. The balancing of the first game was good so you can use it as reference.
