Well I'd be interested in this but I doubt anyone else from ETc would be interested.You can feel free to contact Jay or Darkness (the leaders of ETc) about this though.
You don't really need to be a member to suggest that lol,indeed the original version of battery is rather difficult for allies,If they wanna go from side way they pretty much need a uniform for that but good luck trying getting one
Battery sucks on allied side mostly because they can't blow up the side door like they can in a different version of the map and the only way to get in through side way is with a uniform but good luck getting one. Fuel Dump sucked for allies again mostly because the spawn at cp wasn't available. Railgun is really not Axis friendly that's all i can say about it
Indeed it is a mod related bug which was fixed for the 2.77 version of legacy and until that version of legacy is released,pretty much removing level 4 for medic fixes the issue temporary.
