About Stun threshold and the build without Energy Sheild. Needs help

before 0.2.0 my sorceress did not have problem with Stun. Now it is a biggest problem for my build. I can not cast, can not run away or jump.
T15 maps is too dangerous for me.

I does not use the shield ( Converts all Energy Sheild to Mana ).
HP = 1
Shield = 0
MP = 6700
Can you recommend me to fix this problem?
Is it possible without disable "Converts all Energy Sheild to Mana".
Big mana = huge damage for my build
