3D VOIP is something we'd all like to have, but while it is technically possible on UE3, it's a performance hit and a half that we're not sure is acceptable.
Thank you for the answer. I think it is a simple feature (not in coding, I don't know about that), but simple in that in is a very intuitive way to keep people together and working together. Even without a formal squad system, you can easily get a fireteam sort of group working together on an objective. Not to mention filter out from team chat all the stuff that only applies to those next to you. "grenade!" "Gimmie some ammo!" Those sort of things.
Maybe incorporate a third party app like Mumble?
My list of things to leave out or change would be fairly detailed and tedious. Generally, I like the gameplay experience that IOM gives to player movement and weapons handling in RO2. Zoom if you must, but less, the same for all weapons and please make it independent of ADS.
These things lead to more cautious movement, a slightly slower pace and people relying on their brains and teammates more and not simply sprinting through fire and outshooting everyone in their way.
For gods sake, no leveling......
I'd love to see a dynamic cap system, to increase the replayability of maps.
A deployable squad specific rally point type system instead of spawn on SL, with less fixed spawns. This alone provides incentive for squads to stick together. Now, it's often the correct tactic for the SL to hide and spawn out his squadmates who run off ahead on their own. With a rally, the SL is free to lead.
If there are transports, keep the distances between spawns large so people will value and use them. I've yet to see a transport in RO2 full.
