Today I got invited into a match, haven't played Team Deathmatch I think since the first or second week since the game came out. But compared to the other modes, it felt tedious to me now.
Never noticed it being slow, it does feel a lot less entertaining. I generally get more then half of our team's kills and it's really not that fun trying to carry the rest of the people on your team to victory when they don't seem to want to work as a team.
It does at times for me. Mostly because some of the maps, IMO, seem too big for 8-10 players, and I wind up wandering around half the time trying to find anyone to shoot. No problem with that in Conquest and Power Struggle obviously.
LOL.....I probably should been more clear by saying, "less exciting". There is a bit more emphasis on teamwork in the other modes though, so the brawls tend to be a bit more fun.
