Help with Thugs/Poison pls

I've run into a big problem on my 45 MM.

I respecced him, and got rid of some guff (this is my highest lvl MM ever) and I respecced him with the Leadership pool - and now he's just dying from end issues. I'm slotting end, I've got fitness but he's effectively crippled now. I've got another respec or two available to me but I'm struggling.

Any advice would be appreciated. I've heard this is a potentially very strong build but it's not much cop at the moment.

Of course I would like to see your build. I assume you slot some endurance for your equipping and upgrading. Some poison powers take more endurance reduction than others. Alkaloid can be a real pig. I usually slot 40% endurance reduction in assault in and 80% in tactics, then toggle off tactics when there is a real endurance crunch. Remember, the click will use more endurance than the toggles.

Questiions I have: Are you running noxious gas on the Bruiser? Are you running hasten? Are you spreading your envenom and weaken around? How do you approach groups? What is your strategy for resummoning minions?

Must admit I've not slotted any of the poison powers for End redux. I'd not had a problem prior to the respec so figured that just slotting for End on the Leadership pool.

Yes I run Noxious Gas on the bruiser, no Hasten, and I've slotted both equip and upgrade with End Redux. I will always wait til I've recharged my End before setting out.

Five or six slotting Envenom, Paralytic Poison, Weaken, and Neurotoxic gas by the upper levels is how I approached /Poison. A solid endurance reduction in all four is recommended, esp paralytic poison and neurotoxic gas.

edit: and YES, Thugs/poison is a strong build, built for bringing down the toughest single targets. It shines against bosses, less so against full rooms, but Bruiser is always there for you in the big rooms.
