Yes they have. they wouldnt be able to test the internal build without updating singular. It does seem to cast chimera shot on single target trash mobs, just not on target dummy or bosses. not sure what is up with it but the DPS is only slightly off what I do manually so i dont mind it. Just wondering if it is designed that way for a reason.
Same with feral druids, trying to mangle, but has been moved to bear form. Nothing to complain about, they released a test version just so we could get the bots going again - better than nothing. Still works, just killing a bit slower.
