The most recent Bullroarer build has "the new" animation once again. And there is no toggle option! The animation has changed slightly, but it is no less annoying, confusing, flashy and simply painful for the eyes.
It would be really nice to have an official comment on the matter. I hope you, SSG, will keep to your promise not to bring it back on live without a toggle option. It is a serious gamebreaking issue, not just a matter of taste.
