When you say "there's nothing innovative about it" regarding hearthstone, you could say that about several of the games Blizzard has made.
WoW is a direct, improved copy of EQ and others. The default hotkeys for EQ and WoW were even the same - NumLock was autorun on both.
How is this a bad thing? You could just as easily have critiqued google for not being "innovative" - they weren't the first search engine. Taking an idea and executing it well is a skill, and a profitable one for Blizzard.
