Re: AION: The tower of eternity
The game has been out for over a year in Korea, so it is pretty polished. You can solo well, you can even hit lvl 50, but you need a group here and there. Quests will give you enough experience untill lvl 25 (that's as far as I've gotten), but you really have to do all of them, otherwise you will have to grind. Grouping for elites is not a bad idea if you miss some XP.
Flight in Aion is limited to certain zones/areas, so to help with this there are also flight paths, depending on the area. Using a flight path to get to an area will not exhaust your aether as you are using some form of spiritual bird rather than your own wings. It is a much faster means of travel than standard flight. You really get to use your wings after you hit lvl 25 in the Abyss. But even though you cannot fly in some areas, you can always glide. It helps to move faster in questing, to lose aggro or you can use it to catch up to enemies.
