I think we should change infection because it is dying. I have some new map idea's: Jungle Map, & City Map. Also i think you should add a texture pack to the game to add the feeling to it. Furthermore i think we should get a new spawn that is more exciting. Note: If you have any other idea's or problems please leave a comment.
Why is your name in the title .. I see no point of resetting Infection when they could just re-do it.. all the reasons are you listed (new maps, spawn and texture packs) can easily be done but it doesn't require a reset.
I believe infection needs help but this Isn't It, Some new maps= Yes Texture pack= No Its not worth It.
I agree infection does need some changes, but there is no need for a texture pack. Mainly because some people lag like a ton when a texture pack is being downloaded while in a game. And sometimes they could get kicked, which is really annoying.
