Since MMOs have removed the healer class. Why not the tank as well? A group is FORCED to have a tank, without a tank you can't do anything. Granted, a healer is beneficial...but not nearly required as a tank role is.
Now, I'm sure there are some that like tanking...like wise...there are some that like healing. But, a tank is just too required in a MMO. Plus, tanks are so rare to find....even rarer than healers usually are. This makes finding groups much harder.
Removing the tank would speed up the group gathering process, remove the forceful need of certain classes in a group and this benefits getting into a group quick and easy. Now, could just remove both tank and healer...this way, no class is forceful needed. Then everyone has a role to play in a group, and you don't wait 30 minutes to over an hour (in the lesser populated MMOs) to wait for a certain class that almost no one plays.
MMOs should just keep the most populated roles. That being damage and support. These two roles are the most common (so much easier to find a group if that is all there is). This would also help balance, and make PvP far better as well.
