Did you get all the shield stacks up on your slaves? without that yeah you die fast, but with it they dont seem to have changed at all.

and to log into that toon, as per blizzard's usual suggestion, create a new toon(lvl 1) log into him, then log out and try your main. as usual disabling addons may help(even though they are on the others if any at all), and last option log onto new server, create new toon, enter toon, exit, delete that toon, come back try again.
