I've been working on a new XTA version with Deadnight's permission (though he admitted himself there is no real official releaser of XTA versions now)
Non-balance stuff:
-addition of the new BA units (with new lua scripts)
-cleansing the bloated lua-widget list
-removal of ridiculous idle com behaviour (srly who made that?

-toning down some effects (maybe)
Balance stuff: basically stuff that has already been agreed upon on the forums
-raven damage nerf
-proper cloaking cost for mines
-t1 fighter ground damage nerf (slight)
-ddm range nerf
-sea xD
-more stuff cant remember will update later
Note these are just the areas of re-balance, haven't tested proper numbers yet.
If anyone has any other suggestions post em here.
