Of course there is a need, otherwise they wouldn't be doing it
Say what you want, Metro and CBQ is well liked by many and that has nothing to do with consoles or cod. TDM is best played 8 v 8 and then it is tactical if the teams are balanced (in skill)... This map shown here is also nothing like Metro, Metro TDM is complete crap because the map itself simply isn't well done. This map shown here looks a lot more complex than any TDM map in BF3, with the exception of Caspian maybe.
