When playing a map i Always try to get rid of the creeper spawners nearby but i cant.. why ?
Becaus of the rocked turrets and the amount of time it takes to regenerate my health. IT TAKES FOREVER !
so thats why i think it would be a good idea to have some sort of medic area so you can heal faster.
I have made a drawing on paint on what i think it sould look like. (but im bad in makeing things look realistic) (64x96 pixels) (2x3 ingame)

Edit :
Adding herbs to the idea, here is the "dirty herb.png"

note : tonight i will make the white transparant on photoshop
the herbs can be used to make medic packs and other things (maby even the toxic capsule in 0.7.0 ?)
Please let me know what you think and how it can be inproved.
and thank you for all the feedback that alreddy has been given
