During last nights raid I was getting the feeling that the felguard can no longer perform any other action whilst felstorming.
A lot of times he wouldn't intercept the bloods on cho'gal being out of range of them, and would spin over to them if I'd hit the felstorm ability at the same time as I usually do in this case. Previously I've been able to intercept him into range if I'd started the felstorm early and wouldn't lose more than 1 spins worth of damage. However, with MSBT being broken for me I wasn't able to conclusively prove or disprove this theory.
Has anyone tried this post 4.1 to see if it still works as previous, or if it now works as the tooltip specifies?
