Even if we had access to all the skill lines in game (including the class skills) on one toon, some lines would always be more optimal for certain situations than others. That means you won't have enough Skill Points to allocate to every skill you *may* need, and would still be pushed into a direction that would require you to have the FOTM skills.
So, open skills to all does not mean balance. Its all in the mechanics.

1. Classes dont give balance / freedom (All can have the same skills) do!
Its unreasonable to expect your chracter to be the most optimal build for solo / group pve, and pvp.
2. DK, Sorc, Temp are!
That said theres really nothing to stop you from doing it. Your opponents just arent always going to be mindless AI that practically let you win ala ES.
3. ES IA are fare more dynamic then ESO IA, friend!
