Not enough people play UU for it to be worthwhile imo, and we are overloaded on stickies. The thing about UU that's more important than that is how unstable it is. Even now, Pokemon keep leaving the tier. I got this suggestion back right after Raikou and the other four suspects were banned, and needless to say a lot has changes since the departure of Crobat and Shaymin. I don't see bans slowing down anytime soon. And also trust me, editing things out is a pain...Plat updating the sticky took a good four hours, and that was onyl for about 10 Pokemon. I'm not6 going to give you a definitive no, but be warned that OU was tough, and UU is a whole different animal.
What would you think if I decided to create a UU Threats List similar to your OU threats list? I'd love to do something like that (although it'd probably take a long time) and if I ever need any input on certain things, I'll ask you and D_A about stuff (and if you really feel like it, you could revise it before it gets posted).
Just throwing this out there as I think UU could use a threats list as well.
