Mana buff for ancestral bond

I feel that there should be some further concession to those who loose their ability to use skills to attack, when they take the dual totem keystone. Personally i think an increase in totem cast speed would be acceptible, but hold little hope on its implementation. So failling this, can we see the addition of a 12% mana increase attached to it.

This will off set the relatively high mana cost of casting totems and further increase mana pool so that AB characters can effectively run a few auras for party benefit. Further it will have the psychological advantage providing some greater value for a fairly radical trade off ( loosing ability to attack ) without making the build OP.

As it stands the build has definately gone from being supposedly OP, to sub optimal at best. Show some love plz.

since when is dual totems a sub-optimal build?

I have two dual totem characters. A firestorm witch and a righteous fire totem marauder. Neither of them feels anywhere near suboptimal. In fact, the marauder feels borderline OP, his only drawback is the damage radius.
