I started the league off with Aer0 cobra lash build and I'm barely in to maps but it is feeling just really awful. Mapping is just really painful. Cannot even attempt Affliction stuff because especially my single-target is abysmal.

I know I'm missing uber lab and only have 4 link and shit gear etc. but I've played enough of this game I know something is seriously wrong and getting a few small upgrades is not gonna cut it. I am literally killing some regular rares for a minute or something if they are any tankier. Also if they do any more damage I'm dying a lot and having trouble even getting more levels.

How do I fix this? Any other build/skill I could cheaply respec to? I've never had a build feel this... Unsalvageable. Really painful to even try to get currency for a respec :X
