Firstly--always good to hear more feedback and perspectives from other (and newer) players, as it emphasizes criticisms/feedback made in the past or offers a new perspective.
It's fair enough to say that the game isn't friendly to newer, solo players, as progression beyond mid-game (second class and beyond) arguably slows down heavily and really requires a decent game population for partying (to make leveling less boring and more efficient) and for the market (for populate more gears into the market). Basically in general, I can't imagine a lot of folks motivated enough to solo all the way to 4th class (let alone 2nd and 3rd classes) on their own. As someone who observes yellow egg shouts and as a Discord admin, I've definitely observed the initial enthusiasm of incoming players (especially OG folks who just found out about this server) and how that enthuasiasm dwindles down as they struggle to progress through the game on their own (unless they connect with a guild or group of other players). Definitely sad to observe this, and kudos to the players who offer their time and resources to help out newer players when they can.
And what has been keeping me around lately is primarily my guild and circle of friends that are still around (not only in-game and through my regular dungeon runs, but also outside of the game on Discord and elsewhere doing other activities). I'm sure without these interactions, I would have little purpose to continue playing the game. If anything, the game has been a side game that I log in 1 hour per day and won't be a main game until things change up.
I'm cautiously optimistic about the Xenepic migration, which I figured is the reason for the lack of any changes these past few months. Based on what was pitched out in the following two places (and whatever Xenepic revo videos out there in the YouTube world):
I think it's rather hopeful that the Xenepic version would offer more features and activities that new players (and even old ones) can participate in (e.g. gathering, harvesting, even questing). Of course, those features and activities would be short-lived if it's still not friendly to newer players. I imagine that fixing up the quests (and even the folklore--which I've mentioned a few times in the past) would be one way, out of many things, to support incoming players. Overall, it's really just a waiting game at this point to see where it goes once the new client rolls out.
As for the issue of events catering to high level players, there's already two upcoming events that isn't barred by level:
I feel the criticism made about some events and high level players is partially inaccurate. While the events aren't barred by level (basically accessible to all), higher level players (who basically have played the game for a long while) are likely to have more knowledge about the game and what gears/tactics to use, hence you'd see long-standing guilds and players participating and maybe even often winning these events. If a new player were to invest time in learning the game (which to be honest, I can't imagine a huge motivation to do so if doing it solo), they could eventually be on par with some long-standing folks. It's probably more accurate to say that the events aren't friendly to newer players who don't have the extensive experience to use as an advantage--which is what others have mentioned so far.
One suggestion for the GM team for events is potentially along the lines of more social events catered to newer players. We have plenty of competitive events so far, which is great especially for the retained player base. Maybe trialing out some dedicated times where GMs could facilitate a meetup of new players with the purpose of bringing newer players together? If advertised well enough to make sure it's known around, it could potentially help with folks networking. This could work if there is a decent inflow of new players around (which sadly, I don't think it's that decent of an inflow). It's also a band-aid solution, but worth throwing this idea out.
Anyways and lastly, kudos to the dev and GM team as always. Worth reminding that they're volunteering their time and energy to keep this server around and engage with the players (on top of their work and other real-life commitments). As someone who was in school and working, even volunteering for Lexicon stuff (+ managing a guild) can be quite a bit and requires some innate motivation to keep it up. That said, while I can be inpatient sometimes about how this server is progressing (and despite all the feedback I've given), I am understanding and patient with the pace of things being changed around (and have to appreciate the dev and GM team for what they have done). Of course, all this is not a good enough reason to tell newer players to keep on playing, but maybe at least a reason to stay in touch with the game and consider playing again as things change up over time.
