If you're interested in the IP and enjoy playing a variety of characters than you can get a lot of enjoyment out of the game. Once you dig deeper though you will run into the problems already mentioned, terrible hero balance, boring item system, glacial pace of new content, etc. Problem is only 1-2 of the people there actually play the game in any serious manner, which you can easily see in how poorly tuned the loot system is. Take the raid for instance, I've completed it at least once, many times twice a week since it was in beta, yet only found 1 boss drop(Overseers Mace). So instead of having the thrill of actually finding loot we have to buy it with currency, then reroll it a bunch of times...yeah don't get me started on how badly I want to rip the entire rerolling system out.
