Valks little buff to make them more useful

Hey all,
todya I came up with this idea:
the more damage a valk does, the more the attackspeed raises in a 2tile radius.

so for example, valk did a total of 200 damage so far, she is level 1 giving her and the group around her in radius 2 more dps.

I am bad with numbers and don't know exact amounts, but tell me what you think and ideas for better numbers

lvl1: 1%
lvl2: 3%
lvl3: 5%
lvl4: 10%

Sure. Seems good

Bump will add poll

edit: 750 posts, but no clue how to add a poll, did it before, how? :P

Regardless of how they do it, this is absolutely the next troop SC should buff up to make more useful. Valks are the opposite of what Hogs used to be - they are essentially useless, with the possible exception of being a cc defensive troop.

SC, fix the Valk please!
