ninja/rogue going to be over-played

[Nekodar]

My problem with the new class, is that DF is already a horrible queue as a DPS class, yet they are adding yet another DPS class.

It will only make the Tank/Healer shortage in DF worse still.

For a week or two maybe...
People that like to tank will continue to tank
People that like to heal will continue to heal
More tanks/healers would increase available tanks/healers for a week or two before there is a shortage again

More tank/healer classes will not change what roles players choose to play in the long run. It will just give tanks/healers more jobs to pick from.
