Damage Mitigation?

[BlackJAC 3]

Not really had experience of using VD (sounds dodgy, eh?) myself, but from what I gather it's not until you've pumped it up a little and have a semi decent head of the corresponding enemies you want to target does it start to bloom. Early levels, and as you've found, it kinda sucks.

 

It's also more effective (for gaining xp) when playing multi-player, however, it's not very nice nor fair going into multi-player and lagging someone elses game just so you can level quickly. I've had it happen to myself more times than I care to remember whilst in the desert and it's on par with duping when it comes to spoiling the game for others.
