Have you seen the trailer? It pretty much answers your question. They do give you access to long range weapons, but it's not going to be some type of primary. Like when they are on horseback, it looks like you can use guns.
After GW and secret world i doubt ill ever play game which requires many hours to lv up character while being locked into a single combat mod .
I think this is what the game is going to be. Class specific action combat. Though the classes seem to be pretty flexible like the Magician. She can use mid-range and hand-hand combat.
