need help for ed trickster in HCL

this is my first shadow/trickster ever.
my profile is public, char = ischarioth.

atm im hybrid on extremely budget gear. cost me all together like less than 100c.

life/es = 4951/2222 lvl 87.
my question is should i go CI? i would lose acro + phase acro on the tree, but my es pool would be around 9k i guess if i invest a couple of ex.

id lose most of my attack/spell dodge and id have to give up on flesh and stone sand stance, but will be chaos immune, the effective "lifepool" will be higher and the dmg will increase.

is it worth changing the build into a ci version or would i make it weaker despite the investment?
