1. I believe this is being worked on at the moment, though you can already get on top of most buildings already.
2. I also think landing flares could be of good use in Reborn, especially on that map TS_Isles where there's a good amount of congestion in the GDI base.
5. I see spawning particles already for the GDI war factory, though I could argue that Nod is actually Protoss by warping in their vehicles out of thin air. :iiam:
10. 400 credits is already a good starting amount since at that point you could only buy an infantry without spamming vehicles from the start.
11. I agree, the barracks for both sides, especially GDI's barracks needs to be widenened a little bit, and the beds in the HON cause a lot of rubberbanding.
12. Tiberian life forms are good for a seige/invasion map like RA_SovietInvasion_CoOp that zunnie made for APB long ago.
14. I think that the Mammoth Mk. II just needs a movement/maneuverability increase, and that its chin turret and SAM system should be controlled by other players that enter.
