It is required to spend a looooot of time to improve your character and reach high lv
or
you have 15 alts which you can lv up to top within a week or 2?
Personally I like mmorpgs in which abilities, gear, completed quests, "artisan profession" and levels on a character take dedication and months to achieve.
I like it when after reaching high levels you get start mid way (mid level) a second class on the same character and switch between the classes at an NPC, usually by completing a lengthy and engaging/challenging quest
I hate mmorpgs in which players have an
@accountname with 15 characters, each one for different function:
Pve dps class
Pve tank class
Pvp dps class
Pvp tank class
Farm A dungeon class
Farm B zone class
Crafter
(I may come off as hardcore but the reality is that I dont have as much time as before for mmorpg. Still I want a deep and challenging game)
