I've been avoiding MMORPGS games on Blockchain since MIR4. Currently the games in this niche seem to me "stuck" in gameplay or in a totally automated way. Your post made me want to research this game a bit more.
I don't know what MIR4 is. This one is admittedly a grind, but presents a lot of challenges to the player, and that's what we want. Loot is very hard to come by, and even trash drops are uncommon. Makes it feel worth it when you get something.
MIR4 was one of the pioneers in adding MMORPGs to a Blockchain, check it out here;
