when i switch from a form directly to another with the new form to form included in patch 2.3 closetgnome equip me the healer set (default) instead of the good cat or bear set, is this possible to fix it ? this will really help.
Cause: Blizzard's "fluid" form transitions are anything but. Rather than switch directly from cat->bear and vice versa, your current form is cancelled (putting you in caster, even if you never see it) and the form you are switching to is applied immediately. You can test yourself by trying to switch from bear to cat while stunned - You'll go to caster instead.
So what Closetgnome sees is Bear -> Caster -> Cat. It will equip the caster set and then try to equip the set for your new form - But fail because of the weapon-swap GCD.
Knowing that, macro one of your healing spells like so:
/cast Lifebloom /equipslot 16 Healing Mace of Pwn /equipslot 17 Healing Offhand of Win
Now, remove Closetgnome's automatic switch for Caster Form. When you cancel a form and cast a heal, your healing weapon(s) will be equipped at the same time as the heal is cast. On the same token, Caster Form is no longer invoking a weapon swap as soon as the game sees it, and your feral weapons will be swapped correctly as long as you're not doing crazily fast switching.
Another advantage to this is that if you powershift for energy/rage, you won't end up with a caster weapon equipped for it.
EDIT: Messy macro.
