Duty finder bring the casuals and hardcore player together is a disaster
Yes, it is a disaster. SE is trying to use the duty find to bridge the gap between end game hardcore content to the casuals. Back in the old days like EQ, there is no way for casuals get into Plane of Fear (end game dungeon at the time) without a guild with 30+ people and 4+ hours daily. If you die, you lost exp and you will drop from lv 50 to lv 49 or more. As you can imagine, these contents are really for the hardcore gamers who have a lot of time. I didn't have time back then so I never had a chance to get into Plane of fear until the next expansion pack come out.
Now, the duty finder is so user friendly that it will allow ANYONE to find a group on any dungeon include end game content such as Garuda HM, Titan HM, and AK. The problem is, it also bring casuals and hardcore gamers together in the very same group, and this is where all the fighting, attitude problems, swearing begin.
