I took the 16th off and am begrudgingly accepting that I'm going to be spending a large portion of the day getting RDM to 60 in PotD. There are a few spreadsheets and graphs going around with some numbers regarding xp, time per run, Armory bonus at 0. 50 and 100% that give a good idea on how much time it will take to go from 50-60 in PotD. Best case estimates with 100% Armory Bonus and 10 minute runs non-stop floors 51-60 is about 5.5 hours with worst case being 0% Armory Bonus with 20 minute runs and that's like 12 hours. I'm guessing if everyone has the same idea as I do, I'll be able to get a good group and plow through 50-60 on RDM (and SAM when I get around to it) in roughly 7-8 hours doing nothing but PotD. Which means when I'm finished with it I'll likely have an i235 minimum, if not i255 weapon when I'm done which should hold me over through Stormblood MSQ for quite a while.
If everything works as planned, I'll be level 60 RDM on Day 1 of early access and then be able to start on the MSQ proper on Day 2. I may go ahead and do SAM through PotD during the rush when everyone else is doing it too to get it out of the way. We'll see though. I stoked for RDM and SAM the most, but the changes to every other class are exciting too so I'm not worried about finding a class I'll enjoy playing and taking through the MSQ at my own comfortable pace.
