I would leave Sniper and Spy out. Seriously, although I guess I'm pretty alone with this. Snipers only *really* interact with other snipers, and spies are totally useless against humans (invisibility is lame, and disguise < spy check), so that leaves them as sentry killers, and I'd rather see "fully fleshed out sentry combat" than cat and mouse games between engineers and spies. I'm not sure what "fully fleshed out sentry combat" actually
means though.
I guess I'm all about the action aspect of it. Teamplay, yes, of course - but in fractions of seconds, teamplay that works mostly by "who moves where and shoots what". I think it's great to move in packs with a good mix of classes, but I'm not so hot for "first the spy takes out the sentries, then the pyro sets the minigun on fire, then the engi removes the pipebombs with a EMP nade, then the scout wooshes by and caps".
For the scout... WolfTactics and Urban Terror had/have "ledge grabbing". TF2 has a pretty neat double jump. Unreal Tournament has dodging and wall jumping.... so I say, let's have ALL of this. Also make the scout self-heal! Yes, this needs to be wisely tuned, BUT: the idea is that it's very easy to kill a scout, but if you just damage them slightly and they get away they're nearly as good as new. Even if you hate all the rest, consider this: make the scout an acrobat, rather than just a fast runner.
I don't know where I have this from (it was somewhere), but: if the engi builds lots of stuff, let other classes modify them? Dunno, along the lines of "can build a healing station with the help of medic". Or, the supply station can be upgraded to heal faster by a medic, a sentry can be upgraded in the respective departmens by minigunner, soldier or grenadier, a scout can make a sentry aim slightly faster... okay, maybe these ideas are daft, but the general idea is, don't just let the engineer play with his sentries while the others play with the enemy.
Since it would be really cool if the engi could build dozens of things, either all other classes need lots of toys, too, or they need to get involved in the engi fun. How about "battle stations", which can be upgraded a few levels.... and are not very good at fighting automatically, but can be manned...and depending on what class is using it, it transforms into something slightly different?
Hmm, enough random ideas for now
