Ultimately MNM feels so weird.
It's got a lot of premise but feels severely hampered by lack of foundational direction.
Take the "leveling goal" they have implied that solo players should be able to kill, reasonably, blue mobs in order to level and groups should be focusing on white+. Most mobs are so over-tuned in the late levels (50-60) that you either need a group to keep a reasonable pace on blue mobs OR you are of a class that is hyper over-powered. Most people that I see "SOLOING" are doing it with the assistance of a out of group box healing their leveling character OR they are dealing with massive downtime of the mana regen system (because, for some reason...meditate ends at 225).
Many classes are in a state of "we'll fix it in post" with some classes being WILDLY OP and others being passable (some being severely underwhelming) but ALL classes being in a state of "Almost done". Elementalists have a whole line of spells that SHOULD be fleshed out (their blast system). Shaman are the most underwhelming healer class with their HoT healing a baseline of 225 (clerics get a 1600 heal after 6s) when mobs are hitting for 120+x2 every round. When they do "Fixes" they feel more heavy-handed than really "good" like the bard charm "fix" that made bard charm nearly useless if a mob so much as looks at the charmed mob (Ironically...still OP).
Finally you take the elephant in the room, "End Game". You have the stated dream of islands...where you gotta farm shit to build a boat...chart a course...and then go to an island (Non-instanced) where other people are already. So you are gunna constantly be fighting for camps and then the end game is you fight for camps after dumping a time into a process.
The sad part is, it's a decent game compared to 90% of the mmo market right now. You have empty husk asian games that have beautiful worlds and 0 personality. You have OLD games like EQ and WoW that are past their prime but filled with content and autismos fuckign things up. You have unreleased, pie in the sky games that will likely never come out and will die in the process. Then in the midst of all of that you have projects like this and AOA where the scope doesn't seem too monumental and the team seems like they can accomplish the goals they are looking at, the hope is they can actually accomplish what they intend..
