Gemless Spells

[Makinus]

I´m thinking about a mod that would exclude the gem requirement of the spells that need gems, but i want to balance these spells with the others that are already gemless... The idea is to eliminate one of the causes of micromanagement...

So, i want to see some ideas of how this balance could be achieved, i was thinking in increasing the fatigue of the spell and/or the research requirements... What about if a 1 gem spell converted to a gemless one gets double the standard fatigue? Would this be enough? A 2 gem spell would get triple the fatigue and so on...

Increasing research would be another way of balancing, but my preference would be working with fatigue only as research is a one time difficulty, once researched the spell would be unbalanced with the similar ones....

What do you think?

BTW: the spells i´m thinking about are combat spells only. Rituals, summoning, etc. would remain unchanged...
