Man, we already have too many game modes.
The player base is already far too fragmented between different game modes as it is, and adding more will only get worse when player numbers dwindle further. Especially without reintroducing dedicated servers (which also brings with it a sense of community - playing on the same server regularly/familiarity with other regulars, etc).
At the moment it's in shambles, and adding to the problem by introducing more fragmentation won't "take BF6 to a new level", it will assist in reducing it to a worthless pile of rubble when we all sit there for 5+ minutes trying to find a simple match, give up, and go play something else.
