I did see someone make a Blizzard comparison earlier, but it's a laughable one. Blizzard would never constantly redesign their factions and break abilities, nor make so many schoolboy errors with regards to basic localization and syntax. There used to be (andI assume still is) a running joke about CoH2 being designed as an e-sport, but there simply isn't the basis there for any kind of strict high-level competitive play. No serious RTS continuously redesigns factions/civs or core mechanics and expects the tournament crowd to take the game seriously.
Numerous mods are more polished and cohesive than the live game; we can argue about faction design and unit balance, but in terms of a product looking professional and correctly informing the player what's going on or what something does, that is simply a statement of fact.
Blizzard just rapes their players with auction houses, which is fine. It's okay that they shit on all their old wc3 players and released a broken as fuck 'remaster'. And Wow is such a bloated pos they can't manage it anymore - classes that people have played for years are gutted and reshuffled because why not. I took my nose out of Blizzard's ass a long time ago because they're not even remotely the same company.
Sander & Co have, imo, ironed out the worst of the kinks and generally the balance is about as close as I've ever seen in my 14 years of the coh franchise.
