spotting wave: just a wave for recon that will go ignoring walls and spot enemies
heal grenade: grenade with medium blast radius, blows up on impact, more heals on direct hits,
lets say it has phoenix nanobots inside 
revive grenade: grenade with small throw range, and small blast radius, small fuse time, revives players around it
(to make these grenades funnier lets say they deal small damage, getting hit with metal ball hurts!)
i would like to see projectile weapon with damage drop on, idk what it would be bow, compound bow, rail gun or maybe huge ass crossbow with modernized automatic german elevator
i wasnt going into numbers because those are just ideas, maybe i will add more
