A pretty respectfully worded post overall. As a member of the balance team and a tournament player, I'd like to clear some things up though.
Call in vs. constructed inconsistency is annoying, but I think the more important question on that front is if the implementation in each case makes for better gameplay. Why keep a unit as a called in unit if this very aspect causes problems (balance or otherwise). Sometimes switching a unit from a callin to being constructed fixes real issues in the game. That said, I am personally of the opinion that units should default towards being constructed instead of called in. On another point, frankly, what people wanted from this game or what people decided about this game in alpha is completely irrelevant. Everything was different back then, and those opinions were held based on factions, units, and gameplay systems that were entirely different. If anything, game design decisions/perspectives held early on in the games life cycle didnt seem to make for a game that was fun to play or balanced.
As for polish and bugs, thats mostly just out of most of our hands. Mods are built by miragefla, then when they go for live implementation, theyre rebuilt by andy on the relic end. No one else really has direct control over the implementation and polish of these changes.
