I remember being chastised when I was a group captain for dropping my bomb by the only soos.
The way I play it is, Ill drop the bomb if I think our team is overpowered. Last night I was in a game with living dead and his army of 6-7 sub group capt. players
I ended up losing but I was able to hold off a few waves of attacks by flying without the bomb, then picking off from the highest rank down.
You simply wouldnt, in that situation be able to hold off a wave while ur slowed by a bomb.
If I see our team has chasers like boang or harley on it, than I would keep my bomb and try to go head on.
Its whatever the situation calls for. I dont think their is anything wrong with the chaser approach.
I usually look for who is a chaser and whose the bomber in the advancing wave. I dont worry too much about chasers passing me by because all they can do their is wait which can be funny sometimes
