I voted a 4, but only based upon my own experiences, my own perspectives, and my own independence in the community. Also, because the only game I play is Eden Eternal.
I liked the patch. Honestly. The dungeon limit was greatly flamed and scorned over by players to the breaking point that many quit the game just from hearing it without trying the entire results. However, from my own time playing in-game, it's not as heavy of a loss as many have believed. Trial weapons drop faster than flies in a refrigerator, and due to that their prices have sunken hard in the market (armors are a different story). Additionally, many farmers were upset due to the difficulty of accumulating mass gold amounts, but I've noticed many found alternatives.
There are still problems, however.
The new exp curve is WONDERFUL if you want to be able to level to cap really really fast. But at the same time it makes the rest of the game speed by so fast you wondered what the heck just happened. I liked the curve before; you were able to stop and smell the roses--er, I mean grind to your heart's content. But now, even when it's good, it poses problems regarding "entertainment" values in EE.
There are other small problems, like the continuous random trollpaca disconnections and that the TW quests weren't re-implemented, but imo those are small-time problems compared to the big picture. EITHER WAY, actions MUST be taken to fix them instead of just discussing them with the devs.
GS's are active and vocal, and I like that; though I know many wanted a better choice for GSs due to how "cool" they would be with them; that's not for me to decide, though feedback on each GS should be reviewed and considered. Ticket responses are quick, events are numerous, all's good.
Of course, though, this is my own opinion; I take things as they go and make the most of it; so far it's not extremely game-breaking, but just warning that the contents are starting to cut it really close to that horizon; you should seriously discuss this matter with the devs before the playerbase takes things seriously and actually stop playing entirely instead of just afk-ing in-game all day as most of the capped players are doing lately.
In conclusion, it is the weight of the above opinions that my rating for Aeria so far (in extension to just Eden Eternal) is a solid 4.
P.S.: regarding Aeria as a whole, the log out bug is annoying, but after awhile I found the pattern to it; either way, it should be dealt with swiftly. Additionally, I die a little inside every time I post something and my signature fails to show up properly. That is all.
