as the title says, these things are unnecessary but would be cool to have. i feel a lot of the vehicle teamwork things are gone or were never there, and from a sand box perspective i feel they would be fun to have. these are basically all vehicle based and not for small competitive types.
i would like to see a return of sitting on the side of a scorpion. now there are ALOT of reasons why this is a bad idea,namely in a fast paced fight you wouldnt want to end up on the side of a scorpion rather than in it, and having a scorpion with a driver, a turreteer and 4 guys with power weapons on the side could be… a little overpowered. that said, it would be fun to have that mechanic and sometimes (especially in reach) i would have rather sat on the side with a grenade launcher than in the turret. and halo is all about powerweapons, so i say if you have a tank with heavily armed spartans on the side, then fair enough, you collectively found teh weapons and managed to get to the tank with them as a team, you deservethem boost, and its not like theyre invincible either, 2 splazer shots and theyre done. perhaps a transport scorpion could be implemented without a machine gun turret, similar to the transport hornet from halo 3.
also, should the falcon be reintroduced, i would love to see those seats able to be used! if you remember, in reach during the falcon mission, you could actually sit in these seats and it was so awesome being flown around in first person.
finally, although a lot of people hated them, i would like to see a GOOD vehicle similar to the prowler or spectre. if they were made correctly, they could be a fun vehicle. and if not, having it in the game for custom games never hurts. possibly also the long coveted transport warthog
any other ideas or suggestioons, or even things telling me why these ideas are stupid, please say below! i know there are reasons they wouldnt work, but i was too lazy to type them out
