Yeah A2 vanilla is pretty fugly..... I havent played Vanilla A2 in many years.
Actualy, I dont even tend to play vanilla mods even, I always tinker around with the .odf's and balance 'em how I want 'em, mostly cause I prefer to use a little strategy rather than spam units, so I tend to do things like greatly reduce the pop limit (but also have things like research upgrads and sensor platforms not cost for the pop limit).
It could be a pretty cool mod if it did get done tho.. for example for cap ships, turrets/razor/pulse would be the basic weps that autofire, LMs and foward guns (execpt GB fwd guns) would be treated as a special weapon (Liberty for example would be great for raeping bases with their crusier).
proably the biggest change nessacary would be to changed or removemit bombers, as theyd just be way too over powerd in a RTS setting were you could spam them and literly wipe out entire armadas w/o any losses at all. That or properly balance them for that particular setting.
Actualy the biggest across the board change that'd proably get done would be the ranges of cap guns, as in a RTS setting like that, the larger caps would look REALLLLLY silly if their guns had the same ranges they do in disco, not to mention be utterly useless (assuming Im remembering right in that a guns range is determined from the hardpoints location on the model)
