Okay. I think it's unrealistic to hope for new weapons/vehicles/items, at least in this patch. But, I definitely agree that would be awesome.
Anyway. Couldn't we please, PLEASE make a new game mode for Hide and Seek? Seriously, explaining the rules, especially in any clan H&S's we've had, just takes too long, and even then people do all sorts of things wrong.
If we want to make jetpackers harder to hit, just limit the proximity missile. Make it so it has to be closer to a player to explode than it currently is... Mind you, this would make fights between packers harder... But is this such a bad thing? I just came out of a Giants game, and flying headlong at an opponent (let's call it rocket jousting >=D) firing proxes off is seriously fun. If it lasted a little longer, that couldn't be a bad thing.
Definitely definitely make headshots one-hit kills, if at all that's possible. Also, perhaps make a headshot on a shielder completely drain the shield energy and damage the shielder slightly? Then he'd just be sniper fodder.
Homers suck for me and anyone else who lags. Maybe nerf their ability to turn on a dime and hit you in the back? Make it so they curve more gradually? I was even thinking that perhaps flares could be unlimited, but on second thoughts, that may make homers totally redundant (not an altogether BAD thing, in my opinion... >=D).
If we want to make it so there can be a medic, A.K.A. someone running about with a repair gun, we'd probably have to give it some weight (not unlike the popup bomb, just to a lesser extent), just so it lowers jetpacking ability a little, to discourage everyone on the team from grabbing a healer and recharging in battle. Maybe make it so one cannot be healed while his/her shield is active?
When Kabuto throws things, realism should be forgotten about. Stuff trajectories etc., make it so the objects go in a dead straight line, and FAST. It's the only way Kabuto could easily take down that thrice-damned gyrocopter.
Please increase the power of the (un-gyrocopter) machine gun, pistol and RPG. I would absolutely love to be in a match where these are used! Finally, some variation! This'd give meccs the ability to defend against reapers when they rush in with the sword... just mow 'em down with a machine gun. I would also love the milennium mortar to have more troop-killing ability, maybe if it moves faster or increase the explosion radius or some such? Then a team could have a medic, a heavy weapons guy and some jetpackers/shielders.
Sorry for the long post. But I must warn you... There might be more where that came from...
