Blizzard was a great company until Diablo 2. Before that you could buy a Blizzard game knowing that it was a complete game with very few (if any) bugs. In fact, the only patches that games like warcraft 1 and 2, Starcraft and Diablo needed were due to Battle.net upgrades and very minor bugs.
Then Blizzard released Diablo 2 as a half-finished game. Traditionally a story has 5 acts, but Diablo 2 only had 4 "acts" and space to add a tab for the 5th act when it first came out. The Lord of Destruction expansion pack was actually the rest of the original game. Truely sad.
Of course, even before Diablo 2 was released most of the original creators of battle.net and the original Diablo left to make arena.net and Guild Wars because they were disgusted by the direction Blizzard was going in. Even the employees of Blizzard could tell that releasing half a game and then working on a pay-to-play game would be the downfall of the company.
Of course I have been saying this on the battle.net forums for years and you can imagine the responses I get from their loyal fan base.
