Skill required levels

[Kiahdaj]

In my mod, the level cap is 1k, and I was thinking... I wanted to spread the skills throughout the levels, so you will learn some skills at very late levels. Problem is, how can you base a build off of a skill obtained late game?
Because the skill points you would have to use in order to stay alive until that level would be wasted. Do you get what I'm saying?

Do you have any ideas to fix this?
Thanks

In my mods, all skills are a lvl 1 with no pre-reqs and damage is baded off AoE (firebolt more dmg then fireball for example) and alot of support/buff/debuff skills. Maybe instead of skills that are unlocked every 100lvls, do that instead? (I wont hold you for any copying)
