I wish I didn't have to choose my class when I start the game. I think I should evolve into a class. I can imagine having a pool of 300 (or 500) different skills I could choose from, those skills could be morphed too and there could be several levels of morphing.
Depending on what style I liked I could choose the skills I wanted. In fact what if we could "craft" or discover new skills? Like in real life some people have unusual skills and talents, no idea how I would implement something like this in the game.
Also, the way we acquire skills could change, we should have a limited pool from the start and we should be able to spend points on the skills we like. It should be very flexible and if we did not want the way skill worked we could spend that skill point/s somewhere else. I wonder what other players think about it and if anyone could pitch an idea of how to implement skill "crafting", it would be very interesting. ESO could evolve into improved skill system, there is already a good foundation in game (skill morphing).
