I say no.
There will be more than enough skill points available in the game to master any skill line you want just takes time.
And if you decide you want to play a different class you simply make a new character of that class.
A respec option would just be dumbing the game down and needless. The only real reason I can see ESO adding it in as a way to make more money by charging players real money for any respeccing. In which case, my suggestion will be likely be ignored.
