Please stop with the "no duplicates" and pigeon-holing our DPS into tiny windows

[Zojha]

I think exclusion of popular classes would be FAR greater if duplicates were allowed.

It would - The duplicate penalty serves as a buffer for imbalances. In order for stacking jobs to be worthwhile, the benefit of stacking (i.e. job imbalance) needs to compensate for and outweigh the penalty for it. The greater the penalty, the greater the imbalance needs to be for stacking to be ideal. Likewise, the smaller it is, the lower the imbalance needs to be for stacking to be ideal.

At least in pugs, removing it might become a pwetty big issue.
