1-What class can control monsters or animal and can tame them like a hunter in WoW??
2-Which expansion is a must get and that everybody has?
1 - A coercer would be the closest in ability, but not the closest in spirit. Coercers are mentalists that use mind-control and charm abilities to take control of NPCs. Not really a nature/hunter/tamer themed class. Some of the scout classes can get pets of varying quality, but they aren't control based classes.
2 - For the /most/ part you don't really *need* any expansion until you are 50+, though Echoes of Faydwer can be very nice pre-50. You will want that and Kingdom of Sky for the AA alone, even if you never visit the zones. Your best bet is to go find a retail boxed copy of Echoes of Faydwer (Target, Best Buy, Gamestop, etc.). It's ~$40 and comes with the base game and all 3 major expansions in one pack, so it's definitely the most cost-effective method of getting the game as opposed to buying the expansions individually down the road.
