DDO is semi casual until it comes to gear grind. I didnt play it for too long and it wasnt too hard getting 4 level 20 characters and completing most of the content.
And then thats why I quit, completed everything on several characters in too little time, and also the epic crafting grind was just insane and unfun (spend 2 hours trying to make a group for a quest that no one wants to do because it drops your epic upgrades, and dont get what yo need in 10-20 runs).
The stupid grind fest kills the casual / fun aspects of the game.
Im normally not to bothered about item grinding, but having to spend so long trying to make a group, and having 3 day cooldown timers on so much of the high end content is ridiculous. I actually looted a madstone boots once that dropped for my wizard after taunting all the melee classes in my group over who wanted it. I left it there for over 15 minutes while googling it, being undecided whether or not to give it away, knowing it was completely useless for a wizard, but in the end I thought 'I never get what I want in this game anyway, my loot = yoink gimmeh'.
And then the number of enemies you make over looting stuff with your name on it is even more stupid.
