Just played eden eternal and reviewed it.
TL;DR, I can see why people like it but it really just felt like so many other free MMO except you can be all classes with one character.
Your character gains levels and your currently equipped class gains level, which cannot go beyond you character level and you gain class exp a lot faster.
Once your character reaches a high enough level new classes become equip able.
Only unique thing IMO.
Cons:
very bland graphics
very little customization
very few animations for the character
poor pathing and the inability to jump over obstacles and moving up or down ledges makes traversing mountains and other areas really lame.
feels like far too many other mmos out there, waste of bandwidth (opinion)
