Pd2 is vanilla with rebalance game and map system from path of exile, corrupt system is path of exile too. The mod is for people who love play diablo 2 without go to far away from d2 core.
Path of diablo is diablo 2 meet path of exile. Thats why you see both share same feature.
Lootfilter is from slash, i know pd2 use that and most likely pod too.
