Instead of being

D: 9m
C: 15m
B+: don't even think about it

What if

D: 6m
C: 9m (current d ranks switched to this)
B: 12m
A: 15m
S: 18m

So on the casting turn, for instance with a B rank, you would simply need the remaining 6m to cast it. Yes this means KD can still shut it down drastically, but I was thinking that instead of being a full momentum cost you just needeed to use an amount of 3m actions, allowing you to put 3m into your invoke even if it isn't yet able to be cast. Would fix the overwhelming power of KD versus C rank invokes. A 6m (new D rank) invoke would just cost 3m initially then the remaining 3m to cast (or 4m if same turn).

This would mean dev can add invocations to the game that aren't just D rank or useless, allowing for a new element to tweak for balance. Meaning something like divine judgement or the weaker hexer invokes could be put on 6m, shine knights 12m, and new skills could get slapped with 6m invoke to make them more powerful while giving them the coolness and synergies of invoke. And with the QoL that makes kd not as punishing, longer invokes, like S rank, could even see the light of day!
