I think the notes used to read "Unit-frame addon of awesomeness. *WOOF* It'll bite your face off!"
That's pretty close to verbatim, if memory serves. And yes, the current "dog-themed" description makes me wonder how many folks who'd never tried any version of PitBull decided to skip it with a "WTF?!?"
Ok, I spent a good chunk of time splitting all (hopefully) of the LuaTexts posts into their own thread here. All in all, it was three months and 42 pages worth. I may have missed some stuff, but if I did I doubt it was much.
Firstly, Im getting some nasty lag when raiding, after switching from pitbull3 to 4.
Meh. Nobody reads the damn threads anymore.
Anyway: PitBull4 is an alpha-quality product which is not intended for everyday usage and, due to this, has yet to be optimized for maximal performance. Your problem will not go away until these facts change - probably during the Beta period.
...and I apologize for taking that out on you. Just be sure to try to find a solution to your issues before posting about them. Reading the same thing over and over because people don't research first is tiresome.
