You have Max plunder. Build looks good. B2b haunts. Not much more you can do besides play more or spend money.
You havent been in an eb there in 8 hours. Lol is that what you mean? Try hitting the current eb and not sleeping at all. That'll do it.
We're all weak at some point. Been here two and a half months myself. Work for it. Do ebs. Ambush or haunt and stay active. Buy and sell active allies and you will be fine.
