That's the thing about the classes though. It might be just me, but you might be over thinking it. I mean this:
Only problem is, there's hardly any ideas to warrant an update! No critical bugs as far as im aware to get rid of, and only a handfull of potential changes.
So I believed that it would be best to bring other ideas to the table. Like, for example, a boss for the Ghoul's campaign.
Trivia time: Lux Quadrant
(KCTF03 of my CTF pack for 8bdm) was originally a Skulltag map I made, which was first going to be the suggested map for the Ghoul campaign's boss if it was ever made. It was going to be what it is right now, except for the bases, of course. The idea was to take out four generators in the arena (which open one at a time after something is achieved) to destroy the four barriers protecting the human boss. Aside from the boss's attacks (you name 'em!), human classes would spawn from hatches at various times. Once all barriers are out, the guy goes berserk and the final blow must be delivered.
Meh.
The last time I played GvH, I didn't see any glaring problems anyway.
Good luck, though.
