ok i only ever owned the Dark Crusade version but i played campaign with almost all factions. and played online with Tau and Necrons too. at first it was all cool. possibly the 2nd best RTS i ever played just behind WC3. but patch after patch it just became more and more unbalanced, as the devs nerfed all the cool units. which eventually became everything except the weakest units and the Eldar. rumour has that the devs are big Eldar fans and only ever play Eldar. made the game unfun to play online, and tedious to play in single player unless you play on easy mode... or with Eldar. TLDR: patches killed game balance because devs are dirty xenomorph lovers(just the Eldar).
