Oke some news about newer versions of this game to fix a lot of problems people were having with this game.
You may want to see this video to see it for yourself:

If you're not interested in the video, I'll give a summary of what will be fixed
this year. In the first half of this year Aion will receive it's first expansion and another expansion or major patch in the second half of this year. May it be noted that expansions are not something NCSoft asks additional money for and are free of cost.
Well to summarize, the graphics will be cranked up by a lot. This varies from a new lighting engine to new shadows, more polygons spend on environments and detail, a more living surrounding (e.g. massive flying beasts flying next to you, see video) and a new weather system allowing for summer weather, snow, heavy snow, melting of snow, floods and the likes. In terms of gameplay Aion has expanded it's worlds and is now offering a mount system. Instead of purchasing a mount and just ride it you actually have to catch your mount and then mount it for it to become yours. Also there is a mount fighting system in place. Upon expanding the world this also comes with under water cities, vast sea's and the ability to swim! Also alot of the animations have been redone and now come with collision check for even greater looking fights. There's also speculation (by seeing the video) of new classes using whips and unarmed combat. It's also been known that also Aion will use a talent system next to the existing stigma system for a greater customisation in how your character evolves. PvP and PvE has been expanded by a big deal. There are new raids and instances and also city sieges. City sieges you say? Yes, this gives you the opportunity to create a guild city and create/decorate your own house. There is also the ability to summon giant creatures to help in these fights.
These are just a few examples, if you want a good impression of what is to come this year to Aion please see the video.
