If you are like me then recently you will have received tons of plans. Are these classed as a legendary drop? If so then once you acquire all the plans will you see your leg gear drop rate increase, as you can't get two of the same plan so there will be no more drops?
I thought so. As I've received maybe 15 plans in the last 3 days, it's significant enough to be beneficial long term. That's 15 Blackthorne amulets I may have missed out on
Blues have posted various times on how plans aren't on the same loot table as actual items, just like how forgotten souls work. So no, once you have all the plans your chances still will not increase
