This is just my opinion and not our desicion at all.
I personally ok to make 2th~6th anniv items available again. but would make much more harder to get than before, in other word it could be higher-tier prize in End-game contents. which means will be harder than TTFD. ofc, we must not to drop the value drasticaly. I guess there will be another complaint related to the difficulty, though.
If anyone is wanting to get older anniv item but don't want to make big effort, then I do not agree with it.
But for now, if you seriously want to buy past anniv items, I'd recommend you to hunt ton of crates and sell it to veteran platers whos wanting to buy crates, H90+ items etc.
