The change to the cast time was reverted to the 1.5 second cast time. The range is still 30 yards. Please note though that the tooltip still reads that it is instant cast, but this is a bug that will be fixed.
Drysc has also chimed in with some reasoning on the last minute change:
The instant cast was felt to just be too effective against feral druids, and so the previous cast time reduction to ‘instant’ was reverted through a hotfix back to 1.5 sec. If we had made the change through the patch instead of a hotfix it would have required a new build to be generated, additional testing on that build, and likely a week long delay for the release of this patch. The downside when hotfixing an ability is that the tool tip won’t be updated to correctly display any changes made to the ability.
