@ Paul
What annoys me is know it all people assuming the way they read your comment is the only way it can or should be meant, and then going on to spout off in ways designed to make the original comment seem daft.
For example -
Ez - one every 5 levels
Paul - that makes 51 abilities
Now I only have degree level maths (from a university no less). But I cannot make 85/5 = 51.
One every 5 levels @85 would make 17 spells. He did not state "+All core abilities" neither did he seperate it out into 'core','talent' and 'spec' spells - YOU DID. Why did you feel the need to add to his numbers in such a degree I dont know. And frankly I wouldnt bother reading your post after that, once you have shown me you are going to take things wrong so you can then prove your knowledge, I stop reading as I know there is going to be little of real interest after that type of statement - esp with your passive agressive 'oh I touched a nerve'. Nope I dont think you did - you DISTORTED what he was trying to put - something most people do not like.
Please take this as advice - as I dont think you read his comment very well. (BTW telling someone to grow up and learn something is insulting and rarely going to be effective)

Now my point is that the way I read his statement is that one CHOICE every 15 levels is not much. Which tbh I agree with. I would prefer more 'customisation' even if we were only given some cosmetic choices.
