That makes no logical sense though, if the back-end numbers confirm what you are seeing, since any developer would want to shorten queue times for their largest population (DPS). They've been continually adding changes to tanks to make them more appealing to the wider public, why wouldn't they do that for healers instead of doubling down if they are the biggest issue for queue times?
Even more so since they plan to add TWO DPS at the same time. You would have thought they learned from Stormblood.
