Is it worth if I level to 80 or 85 as a Protection, then level to 90 as a Fury? Any disadvantages here or is it a good play.

No. You should level as the spec you intend to play at 90.
Why? You can use the wrong moves and still kill a mob fairly quick. Playing the specc you intend to play at 90 does not provide any training playing another specc wouldn´t provide as well.
OT: Playing protection is fairly fast, especially if you like pulling many mobs and/or doing dungeons. After 85 you should play Arms. Fury requires a lot of crit to be fun.
