Need advice on my elementalist storm totem build

How about going heavy on Storm Totem according to the thread’s title.
Max it and equip the following target farmable MI’s

(you don’t need level 90 since there are lower levels versions of these items)
You’ll gain lots of power quickly this way

Also augments in every slot, for example: Mogdrogen’s Touch

Let me tell you this. Suppose you have 60% X resist. You then take double the damage from X you would take having 80% X resist. Such an easy fix, yet such a huge difference. No other stats make such drastic changes. That’s the reason why resist should be maxed and even overcapped later if we include debuffs from enemies.
