Agree, D3 looks very boring, compared to MedianXL, D3's endgame is boring, itemisation system sucks, compared to Median, and crafting system in D3... is just a joke.
They made a simple game, that is friendly for new players, but it is too simple to be fun for veteran players, especially taking into account, that you can not succed in leaderboards, if you dont play at least several hours everyday day.
By the way i tried Median just few days ago and now, seeing how awesome it's itemization, endgame, crafting system are compared to D3, that i no longer want to continue playing D3. Only in Median you can feel a REAL equipment diversity, so many options to choose from, and so many combat mechanics to count. D3's is more simple, following a known streamer's guide is the only efficient way to play (for pushing greater rifts). and that 5-6 tab stash - is not enough for diversity, its enough only for a single class, if you play more classes, you will not have space to keep all of their item sets with non-set pieces, it kill diversity and leaves you with thinking "i dont have stash space to collect some experimental items, so the only choice left - following some known guide, that everyone else uses."
