I love BTB, I find it appeals to me more than any other game type.
However i have noticed a few issues with it.
Firstly the map variation is repetitive. There are lots of BTB maps that just seem to never come up for selection. Secondly, Where has all the objective games gone? This brings me to the point that i would really love to see a btb heavies CTF slayer mode.
Much like the CTF slayer on team objective just scaled up.
200 kills falg cap counts as 50.
On to another issue with BTB heavies. There tends to be a in balance trend caused be the spartan laser. Especially on maps with one laser. I would say that all maps with such weapon layout should be re worked to remove the laser. The btb heavies mode to me should be about good use of the Vehicular assets provided. not a race to the laser so one team can go all fish in a barrel on the other.
Plenty of better ways. Like replacing it with a rocket or grenade/p nade launcher.
