both.
the control will be just like CS.
item upgrade and mission just like mmorpg.
people say this is a true mmofps genre.
only games that in this genre that i know of are Firefall, Defiance and Planetside2.
but i heard that a new game call Destiny by Blizzard will fall under this genre too.

i never played Rakion so i dont know what it like.
but from Firefall close beta (i didnt play the live version)
the mission is mostly defending from waves of enemy for a certain time, going to a place to a another in a time frame, operate devices and so on.
there are also lots of instant quest event just like in Rift/GW2. Player can also generate this event by calling thumper(mining device) and other player can just join by helping you stopping wave of enemies trying to stop that device.
