I don't know about other people, but I find the Krait Witch quite intimidating. I do actively avoid her lair when in Kessex Hills. It has this menacing aura about it, unlike the world boss fights, not to mention the fact she is a pain to kill. If I can get a revamped fight with new rewards for free then I'm quite happy. So what if we get a fresh platter of gem store goodies, nobody is forcing you to buy them. For all we know it isn't a boss revamp, but rather a entirely new dungeon. I'm still clinging to the hopes of the once mentioned Crystal Desert expansion, so any living story until then will do.
