You're assuming everything will stay exactly the same post-3.1, even though we know we're getting sweeping changes. If things stayed exactly the same as they are now, including damage on tanks, then yeah not fixing PLD at all will put it in the same position it is now where it takes a significant amount of overgearing to be "good enough" for content that DRK/WAR could do much, much earlier. However, the only thing changes in 3.1 affect are PLD's viability in Savage Alex - content they already overgear extremely and 3.1 will only make it easier to overgear with Void Ark, Island Exploration, and Thordan EX. If PLD still couldn't do the content at that point of overgearing then we'd have an issue needing to be solved, but because gear does alleviate the problem then there's no need for a DPS increase at the moment.

What people want is a DPS increase out of fear of incoming content being unclearable by PLD once again with lower gear levels, which was understandable and I was 100% behind. But now that we know things are changing, that fear shouldn't be as rampant as it was. If PLDs aren't currently clearing A1S-A4S it's not a problem with the job, it's a problem with the player.

Maybe I'm wrong, I'm not really 100% sure myself if my words ring true, but if a DPS increase were implemented now what would that do besides make PLD more viable at lower gear levels for Alex Savage when everyone already has access to gear far beyond that point? Maybe it would quell some fears for the future, but I think they could do that by simply explaining the changes coming in 3.2 since I imagine if they're changing the damage formula for tanks entirely then all 3 tank jobs' DPS will change drastically one way or the other.
