Looking for help.

So just recently accomplished lvl 90, ive been a poets pen volatile dead body swap build, i enjoy it i really do, but considering respec into a stronger single target skill so i can focus bossing and uberlab versus mapping, pp vd is mostly good for mapping and seems my bossing was meh, t15 was possible and then some but i want a faster boss killer and less of a mapper, if i can get both then great but if only 1 then so be it... i would like keep my tree for the most part but if need be i have currency to regret the whole tree... same to my gear id like to keep some if possible but not required, here is my current gear.







Not too worried about map clear because ive a Ranger lvl88 that does fairly well mapping which after changing this jugg ill buy it the same amulet and chest for that acc so i dont need to swap it everytime, thanks in advance, still farily new to Poe compared to some of you all (only have 1416 hours in game). My characters are Veiwable to all incase want to see my tree or view my other characters
