* There is more freedom in making the skills if players can reach no limit. In D:OS EE, it's very silly that we are told we can learn 6 Novice water spells when the game has only 5 Novice water spells. Removing the limit at high levels would lessen this problem and give freedom for the designers to make as many or as few skills as they want.
On the contrary, I think no limit means they have to reign in the number of skills available to a particular school moreso than when having a limit, though I agree a limit does encourage having at least as many skills to meet that limit (but that's not a bad thing.). It's easier to balance around a limit than unlimited skills, and personally, I'd rather have slightly fewer good abilities than more crappy ones. It is silly to have only 5 novice water spells available, though, and maybe level 5 in an ability could let you learn unlimited novice skills, or at least a max of 7 or 8.
I don't see this reverting in D:OS2 with their plans to make way more skills with skill crafting, unless they come up with some other way to balance an excess of skills. Something like increased cooldowns or slightly reduced efficacy of spells for having more than X spells known might work.
