spirit levelup rage dilemma

[Viro]

I play a mage (lvl 15 on hard) and i can hardly use the ice spirit anymore because i never get enough rage in 1 fight as a mage and the spirit always gave me the same 2 upgrades after level-up : ice orb dmg or charger
Both are up quite a bit in rage costs now.
I also can't chain fights together because i take heavy losses if i can't nuke some of the ranged guys at the start, and if i nuke them i'm low on mana for the next fight....... seems like alot of hassle just to cast one ice spirit.
If I get one more of those nice random upgrades (the same one i got so far ofc ), i can't use ice orb or charger anymore because i dont have enough max rage and it would take alot of effort to get that much rage in a fight anyway.
Also fell for the tooltip saying mana regeneration after combat.....pffft... after combat i have to stand around for a minute or more until mana regen kicks in.. wish i hadn't put those points in.

Is there any way to use lower levels of the spirit skills like with spells ?
