I got the skill but it was like +1000+normal gun damage @lvl 10 is it really that weak?

It was dissapointing. It says in the description said +330+% damage. >.<

Does anyone know how much total damage it can do when used with Keen sense? ?_?

it not that weak...however the skill "gun overdrive" is increase normal gun damage, it also base on ur Gun AP to determine the damage...the higher

ur Gun AP...to more damage u'll get....

and also the skill can combine with knee ssnse(which only work on Time Crit)....although i'm don't really want to calculate that damage = =||b

anyway it's not a really useless skill maybe ^ ^?
