Sorry guys but you just don't know how to play RDM if Enspell I&II mechanics throw you off like that, same with Gain spells, if you don't know how each stat affects you then you don't know why it is such an advantage to be able to chose a stat to boost at will.

What you should be complaining about instead is how badly RDM spells scale with skill and how low the caps are set on them, also about how the merit spells should be scrolls instead with merits used to either enhance them directly or generally.

But the mechanics of spells are good, you just need to learn2play and to adapt to situations.
