Keep dying maps/delving. Res capped, 3400 Life. Strange Build(Fire Trap) and Tree...

Hi,
I've got a bit of a strange build. I realised that I have not the dexterty needed for Fire Trap...
Anyway I thought I should keep playing till I've got enough currency to change the build.
I've got my res capped.
My ascendancies are not finished as I hate the lab at the moment.
Maybe it's because I'm only level 63 but I keep dying on delve level 59 too.
Any help welcome,
Thank you very much :-)
