With Kataclysm being the next event in the rotation, it's time to talk about its one big problem, and hope GH takes care of it before the event starts.
For the next Kataclysm, the other three Kat Suits should be made easier to get. They're not worth the fortune you need to spend to get all those Margrel spots at all, because if you have that much money, you're probably going after Black Kat instead, which crushes the other Kat lines with status resistance from other sources.
The smarter and simpler way to do this is to have the Claw, Eye, and Hiss suits be crafted with Kat Tribe Fetishes, the same way the helmets are made. That way, someone might actually use these armors for once.
I mean, Black Kat is supposed to be this really fancy, exclusive endgame armor set, and the other Kat Raiments need the same resources to make them, even though they're really no more special than other offensive armors. I can't imagine why they'd put such a huge stumbling block in front of getting them in the first place, especially when most of us agree that they're useless because of how tough they are to get.
See if you want to see a huge list of potential fixes, here's the thread I bump every Kataclysm due to how many potential fixes have been listed there. You can skip to post number 47 for a rundown of the thread up until that point.
My personal favorite is a mini-margrel boss fights that give a whisker for 100 pages. This makes the event more "farm for a reward" instead of "farm for a single item that you may or may not find to get the one thing you actually do want".
