As a Imperial, I don't give two [censored] about Speech, Restoration is much more useful, especially when it comes to fighting tough opponents like Dragons. I can't bribe dragons to go away.
I love both..
And just to be clear, its much easier to level Resto (spam healing spell, ward yourself every second) than speech..
There is no more wheel (thank you for that) which means you cant talk to 20 random people and raise your skill.
You need to sell a lot of stuff and attempt (and fail) a lot of persuastion attempts..
Starting with speech at 25 is much more important than resto at 25.
With speech at 25 you can probably win more challenges than with 15..
And when you start the game with nothing that is important..
