Oh dear I do love this kind of post as say "I can do it and I am casual, do yourself", pretty much on the direction of "do not change nothing".
Aion do have a huge problem within with new players, as the game "rewards" you with "beeing loyal" basically with beeing easy as you spread your network of friends on the game, and that's something I do always think on: A network of friends do help to improve on a game, every one, and Aion is no exception. Some people do find easy to make friends and they can aid them with a SWB or a Kata run, or some dreds and some do not have that easy way, and I myself I was Officer 4 Asmodian on Retail and it took YEARS to fully make a obsolete 2 officer gear decent. Also, joining the winning faction does not mean be easy, you gotta need score frist if you want to get the medals, and those veterans on sieges will know where and what to do to get a Rank 1 (Wich is a thing I do , but I don't get any Rank 1 on this server, on retail it was very unlikly)
To be honest, I started to dislike this version of the game, as I read previously: It' not fun beeing killed while doing garrisons. And they are right, there is no fun of beeing oneshot by a mass of enemies that makes you have to visit the garrison when it turns your faction again, and that can take hours, I think that other versions are new-friendly, as the Kaisiniel/Marchutan long quest line for gear, wich yes, it was long and hard, but they gear was quite good, and the ArchDaeva update, you could go to some dungeruns like Library of Knownledge and get that gear, then, at the Abyss, you do garrisons and you could run by some epic or mythic bloodmedall gear.
I recently revisited another private server, (Not "Aion", it is another P2W game sandbox that everyone was hyped on) it was itching me, when I did left that game, they were at 3.0, now they run 5.2 , and honestly, they are not doing that bad, they are adding new stuff , self made stuff, constant stuff, I didn't feel like much was changed, just some stuff gone but mostly, they still with somethings that should had gone because they work, what I do try to say is, that EuroAion should be not afraid of touching the game to improve it, of course, they can do custom events, but they should be sure that they are not like the boxes on Silentera or South Katlam , wich it was mostly for gankers. The team could sit, think and wonder: "Is this version letting us to do a lot of stuff we do want to do?" "Is this version really worth it as it is or do need some tweak?" "What does needed the vanilla version and how can I make it better?"
They want to make the game more accesible without touching too much the game? They could lower the requisits of the Soldier's gear, less AP and Ceranium need, they could add MKK entrances at both landings on Abyss so players can go without problem, they could give the same medalls to everyone despite rank that would be only for GP, they could make harder the boss of the loosing faction to avoid beeing disencouraged as it happens frequently.
Katalam is not the best map of Aion, period, if people do want still get intro the map, then we could settle portals somewhere (Sanctum and Pandaemonium seem a choise) to make them accesible again, we do know that when a patch is applied, the maps simply hide, and retail was able to bring Tiamaranta's Eye for a event once, so it's possible to kept Katalam while advancing on patches.
And no, Aion does is not only unfriendly with new players, they are unfriendly with those who make potions, scrolls, items for a living too...
