I am doing co-op with a buddy playing the ninja, and having trouble staying alive on a regular basis. My damage output is only average, but thats due to really bad weapon drops and 10 golden keys that got me about 70% class mods for other classes.
Currently running the build below with 14k shields and 13k health.
Personally I maxed out the middle tree then worked on the right hand one. --- 7+7=cat tango+cash=marshmallows I like spoons There is a direct correlation between the sales of Alphabetty spaghetti and the intelligence of cows

Being able to Gunzerk while in fight for your life is way more valuable than anything the right tree offers and the insane damage bonuses from the left tree and not to be overlooked.
The reason I have two skill points in the right tree is for the Legendary Class mod.
EDIT: It's worth mentioning that "Get Some" allows your Gunzerk skill to enter cooldown while you are still Gunzerking. Couple that with Money Shot on a level 61 build and you can get an additional 25% Gun and Grenade damage the entire time you Gunzerk and whats more you don't get taken out of Gunzerk when you enter fight for your life. --- People think it must be fun to be a super genius, but they don't realize how hard it is to put up with all the idiots in the world. - Calvin & Hobbes
I didn't know that about get some, being as I focused on the middle tree I thought it would beuuseless to me. --- 7+7=cat tango+cash=marshmallows I like spoons There is a direct correlation between the sales of Alphabetty spaghetti and the intelligence of cows
