It's easy to fix this. Just move the power around, if possible. This is the most dynamic way I can think:

Asura Fist:
- Consumes -1 Schwarz Sturm LV.
- No longer generates Schwarz Sturm LV on-hit.

Regenshauer:
- Generates +1 Schwarz Sturm LV.
- Can now be executed without the need of a target.
- If Regenshauer targets an enemy unit, it generates an extra +2 Schwarz Sturm LV, to a total of +3.
- If Regenshauer doesn't target an enemy. The FP cost is halved, as you are throwing punches on the air to warm up.

How about it, people? The idea came from, Orkam Drehen being a skill that rather 'unleashes the sturm built into you' than 'generates more storm', and theme wise, Asura Fist could be one way to release Schwarz Sturm too? (This way can also prevent Spellthieves from abusing this spell's high scaling, making it exclusive for Boxers.)

And the SS generation being moved to Regenshauer is because of two reasons, one, Regenshauer 'really' depends on Sturm to do any (in)significant damage, and to land a Regenshauer is quite hard because of the melee limitation, unlike Asura Fist, which can even be used at random to just build up sturm.

If anything, I'd rather see a Boxer using Regenshauer on the tile infront of them for a 1 Sturm built up, it makes more sense they throwing punches on the air for a 'warm up', rather than throwing a flying blast of energy and calling it 'boxing'. This, aside Regenshauer's relatively enormous FP cost.
