Call me a cynic, but the incoming buffs to DRG are probably going to be more quality of life adjustments rather than straight damaging buffs.
They'll be increasing the MDEF we know. They'll be loosening the positional requirements (probably) to allow Heavy Thrust to give the buff no matter what direction it hits and hopefully allow Impulse Drive to start the combo from wherever it hits.
They'll be doing something with Blood for Blood, but I imagine it will just be adding to the trait that adjusts the LNC form again and probably just lowering the vuln-up we get from it to maybe 20% instead of 30%.
They're gonna do something with recast timers, more likely with Jump, which of course will help, but I'm not expecting anything major. It'll all help, for sure. But eh, maybe I'll be surprised.
