This is a small thing that I have been thinking about and it actually has began to bother me a bit. Essentially at the launch of a new raid tier, all your work in the previous tier does nothing to help you launch into the next tier because you just replace it with crafter gear on patch day.
I get that it's good to have a system where new players or players who skipped a tier can catch up, but really the crafted gear should be a catch up, not a skip ahead.
In this case new crafted weapons for this tier should be i505 and armor/accessories be i500.
Gear you earn in savage should be the best possible gear to start the next tier of savage not crafted gear that anyone can buy off the market board. It gives the gear a slight bit more life than helping you clear the fights you already beat quicker.
And no, this would not make crafting sets worthless, they would still be a viable catch up mechanic for the players who do not do savage or want to change jobs for the new tier and didn't have that job geared. The only big loss would be that week 1 raiders wouldn't have to pay exorbitant prices for gear they will be throwing away in a few weeks.
