But there are a lot of readers not convinced that this would be neccessary at all.
There are a lot of forum goers on the d&d boards that are convinced magic classes should inherently be superior to martial classes. Or I other words a lot people believe a lot of things. And reaver had what I meant correct. Te only limit is the standard no more ranks than your magic attribute.
The beauty of dropping the limit is let's say you are making a character and you don't think its necessary for your design. Well great only take one level, but bob who was shooting more for internal magic power punching holes in people while still being a gangly teen picked on by cobra Kai can keep his strength at 3 and take 6 levels in critical strike.
Both sides can make the characters they want. So unless fun is had by making sure others don't have fun multiple levels works fairly well.
Also no I have not dropped it to .25 yet. I'm thinking about it. It's falling in one of those .25 might be too cheap yet I think .5 is too expensive points. I'm considering multiple options like a pre-req for multiple levels or a higher cost on the first point so the multiple levels could drop to .25 but keep the overall cost fair. They really should of moved to .1 variations in cost, .25 is too large of a swing.
I'd probably drop the cost of improved attribute to .5 first. It really is way too expensive at 1.
