Again, read the topic before commenting.
All characters on an account would share the various reputations to be found in the game, and joining a guild is account wide, not per character.
Are you okay, bro?
I'm not talking about npc reputation. When a player goes around on a killing spree, other players will remember the name. A player that is constantly killing will get hunted. With multiple characters per account, a player with bad fame (bad fame with other players) could easily log into his other characters to wait out the heat.
Inventory would also be a problem.
Only way would be to share character names, inventory and pretty much share everything except combat skills and race/cladegifts. That would not be a new character anymore. Why not suggest for loadouts? makes more sense lol.
My point is ( to be clear, cause it seems you need a map to be drawn) that multiple characters per account would have many problems that cannot be fixed.
If not being able to try other combat styles is your fear, then multiple characters is not the solution.
