I want to share my opinion how the game could be really play what you want

In the endgame you have to decide what kind of damage you wish to deal, magicka or stamina and max one of these to be competitive. This sadly limits the number of viable builds, especially hybrids.

My suggestion:
Each level you would gain one point to put in resources, Magicka or Focus (stamina) they should not increase your damage, only your resource pool.

You would also gain another point to put in offense and defense, Power or Endurance. Power should increase your damage and healing, endurance should give you health and another resource bar which would be used for block, dodge and sprint.

This way we could build pure glass cannon, pure tank, and most importantly a viable hybrid.

I think that armor passives should be a bit reworked aswell, Examples:

Light armor:
- Reduces the magicka cost of abilities by 3% per each light armor equipped
- Increases the magicka regeneration by 3 % per each light armor equipped
- Increases the spell critical by 2 % per each light armor equipped
- Increases the endurance regeneration by 3 % per each light armor equipped
- Inreases your spell penetration by XX per each light armor equipped

Medium armor:
- Reduces the focus cost of abilities by 3% per each medium armor equipped
- Increases the focus regeneration by 3 % per each medium armor equipped
- Increases the critical by 2 % per each medium armor equipped
- Reduces the cost of Roll dodges and sprint by 3 % per each medium armor equipped
- Increases your armor penetration by XX per each medium armor equipped

Heavy armor:
-Reduces the damage taken by 2 % per each heavy armor equipped
-Increases the health regeneration by 3 % per each heavy armor equipped
-Increases max health by 1 % per each heavy armor equipped
-Reduces the cost of blocking and breaking free by 3 % per each heavy armor equipped
-Restores magicka and focus each time you are hit by XX. Can only occur every 4 seconds.

I think that with this changes game would have a lot more viable builds your thoughts?
Keep up the good work zenimax
