For hardcore gamers, not "just playing to play" gamers...
I never really liked Warcraft but I did like Starcraft. However, with this addition, it felt a lot like Warcraft than the old Command and Conquers. You have to memorize the hotkeys for the abilities and etc. if you want to be slightly successful.
The biggest thing I hate in strategy games is resource management. Like Warcraft, units cost a lot of resources, thus, meaning that you actually have to think of the types of units to create to be efficient. This game seems to be built for quick, fast paced games that last about 15-20 mins which isn't what I am looking for. Unlike Starcraft II, in Starcraft I, you actually had the time to build up your base and etc. but in the new Starcraft, I always felt rushed to do the first attack or ignore defensive buildings and create offensive units/groups. Defensive buildings have become incredibly useless in this game, even a few of the first-weakest units can take one down in a few seconds.
When playing online, players will always mass create the same overpowered units which makes things very boring.
I guess what I am looking for is something more like Rise of Nations where resources aren't a worry as they don't deplete, units don't have a huge advantage over another, and every building has a purpose.
I would not recommend this game to non-hardcore gamers unless they are used to using hotkeys.
