Many old addons can work, but i'm asking why there is NO WAY to avoid this:
https://mods.curse.com/addons/wow/category/death-knight
Top 5 downloaded of DK addon: Bitten's SpellFlash: DK and CLC DK , not updated from 6.1, a ROTATION SPELL PRIORITY addon, why is this "part" of an addon still here?! Still in top 3 download? I think because many newbye download it, and then don't use it but let the addon to be a top 5 addon for dk.
Spellflash it's one of the not updated addon that many of my newbye friend install and crash or give lot lua error disabling random addon ONLY during fight.
Why an user friendly addon manager like Curse cannot be really user friendly? Even wow ask you to confirm to "load deprecated addon", why curse cannot ask before download deprecated addon ?
