Mastery signature spells

[roadkillrobin]

Ok so adding masery points do one thing, it adds power to the spells in that Mastery.
Buit what if all Mastery paths had a signature spell that changed when you reached certain threasholds.

I'll make an example here.
Sigmars Radience is clearly a signature spell for Grace WP.
What if it at:
6 points in Grace hit an extra target within 15 feet.
10 points Heals the WP for an aditional 200 hp.
15 points now heals all alies within 30feet of the Warior Priest.

These are just some examples i came up with on the fly.
So lets do another class.

For Black Orcs the signature abillties is imo the War bellows so lets use Da Greenest
6 points now grants 4 points of morale to your groupmemebers whenever it triggers.
10 points restore 20 ap to your group whenever it triggers
15 points now drains 4 points of morale from all enemies within 30 feet whenever it triggers.

This is in incent to actually go higher into a mastery path then to just get abillties. I understand that tactics were kinda supose to represent this. But atm we only have 3 tactic slots (4 at 40) and there's just as many dead tactics as there are tactics wer don't have room to slot. And it also might be a way to bring ballance to unwanted classes.
