Mara 47 hc needs help!

Hey guys,

first of all this is my build


Have 7 points left, and i have no clue where i shall spend them in my passive tree. I'm walking with ground slam heavy strike glacial hammer molten shell LS Reju totem. The problem is i am pretty easy to kill, sometimes it makes me hot, when from 100% u gets 20%, is it normal to tanking with flasks? Any advice would be pretty usefull for me, about gems and passive build.

Get RT, get BM. Get Life Gain on Hit. Get health/regen equips.
No. Even pure tank DOES NOT use health potions AT ALL
