Good guide until I got to your damage up recommendation. Damage up does not reduce the amount of shots to kill, which is why it isn't useful here. There are a couple of guides about this. Also, you say snipers are problems, but you don't say how to deal with them. You should definitely recommend haunt and tenacity abilities. The inkstrike isn't bad, it just needs to be placed well. A little more length would make it better.
