[FRAC-2094] Focus abilities consume more mana than they should

[Razvan]

It's easy to notice if you create a character with 10int (=20 mana regen) and activate frenzy (which costs 20mana). Idle for a minute with just frenzy active and you'll notice the mana drops with 20 every few seconds, instead of being constant (since mana regen = toggle skill mana cost).
