Can we get a better criteria to determine what roles does X DPS compared to other roles? Right now the community is going out of control with various personal 'taxes' that they believe warrants what jobs/roles should have higher DPS and which should have lower.

For example, mobility tax is often the factor for Phys Range/Casters. Using casters for example, mobility wise, SMN is the most mobile whereas BLM is more mobile than RDM currently. Yet RDM does comparable DPS to SMN. This is a major issue that needs to be addressed to avoid certain jobs (such as a Phys Range) becoming a participant solely for the 1% buff.
