Let’s see how it actually goes first, it’s very intriguing. What stands out to me the most so far is that clutches really aren’t a big thing in this mode for Dirty Bomb. On the other hand, that only makes it more exciting when it happens anyway.
I do think Fire Support is actually really important in this mode, otherwise you can easily be starved of ammo. The tactical spam is a bonus. I don’t know about Engineers, but having one does add a lot of pressure for the other team to secure the bombsite and they are decent for defense as well, so I wouldn’t rule it out just yet. Finally a skilled Vassili should be able to make quite a difference, especially if the other team goes heavy on Fraggers.
The map seems pretty good to me so far, sans polish of course.
I think it plays fairly fast, and that reducing the round time should be considered. Perhaps increasing the max rounds instead (games can be over really quickly).
I do enjoy the non-stop action of Stopwatch, but I could see this mode providing more tactical depth once teams really dig into it. It also sidesteps a lot of difficulties and balance issues of Stopwatch, so that’s something… and of course it’s great for spectators.
A big question will be how it fits into the competitive scene. Allowing people to choose the mode together with their map (ala CoD) could be very interesting in my opinion. This would add a ton of variety but would risk alienating those who really can’t stand one mode or another.
