Randomly and definitely not rarely, I am unable to cancel out acid spray or fury with a heal when needed. Not sure if it's a timing issue, I have always found bug form a little slugish for healing, and personally I would never choose flight as a preferred movement mode for a healer either. Really wish the power back mechanic afforded by Hive mind was made available to the normal form also so as the choice to use bug mode or not was not so stacked against me. It seems I chew through more power these days healing in normal form than I did before the changes to Nature were made, making my choice not to use bug mode all the harder. Still loving the DPS changes. Obviously with powers like quantum out there that are ridiculously OP (seriously, maybe just went a touch to far on that one, so powerful, but so incredibly dull to use), balance is out the window, but still, if you're pumping a powers full potential, all the of them (almost) are pretty acceptable.
