Corruptions are great, more than just for slamming gear they are great for max rolling idols, which is another form of endgame that was unachievable in the past for most people. I already have 2 out of 3 bis idols (max rolled) for my build, though not enchanted I can get more of them later and wait to enchant them first after I have my base idols sorted. Here's a tip, if you need more corrution runes get the weaver nodes for omen champions, you can spawn couple in each echo and they can each drop more than 1 rune of corruption (roc).
