One groupable server compared to raid server

[Bakersman]

just a little curious to see what people think of this, i am kinda in mind to create a one groupable server and i am curious about the current databases out there. peq and ax classic, i understand that most would prefer to stick to two databases and i am not really interested in creating custom stuff to the database itself. except for mobs hp and dmg output to make it into a server that is one groupable, 6 man team. instead of the 24-36 man raid, a hard one groupable but not so hard you cannot kill a boss. the reason i am leaning towards this is because it would make epic 2.0 available as well as the experience to get to end game content without having to be in a raid, i do not want to take the lockout timers away on such things as dragon raids, when things become available. i guess what i am asking has anyone attempted this type of server and if so what kind of drawbacks or issues have you faced when attempting this kind of server
