Hand to hand combat isn't a tradition MMO system of fighting and I doubt that will be any different in this game.
I agree they probably won't have hand to hand in this game. Though I disagree with hand to hand not being a traditional MMO system of fighting

.
EQ had monks. They were great. They used martial arts and could go hand to hand or staves. They were fantastic pullers and dps. Groups used to love to have them throw stars at a group of mobs. Then feign death, targeting the one they wanted. They would call a tag. The warrior would now shoot the separated mob to the group. Excellent for when you walked into a full zone, and you need to thin them out to set up your camping spot.
I think they could also sneak past mobs. They were pretty good at using the sneak and feign death to drag your corpse back to you. You know back in the day when death cost you exp, and enough deaths could de-level you

The class was so much fun, WOW is bringing the class back in their panda upgrade. At least I think that's what people are saying. Can't quote me there as I haven't played WOW in years.
So this game may not have it, but other MMO's used them traditionally and they appear to be making come backs.
