Gauntlets will be an interesting change from wands. The changes in Thaumcraft between MC versions are one of my favourite things about TC, they keep it fresh without taking away what draws me to the mod.
You mentioned that you couldn't stop the reequip animation playing.
I assume overriding shouldCauseReequipAnimation() to return false isn't working? It's a Forge method, so it might be worth creating an issue on the Forge repo. Though any fix would be for 1.11.x.
shouldCauseReequipAnimation indeed stops it for most cases. The case here however is any changes to the item while it is "in use" like while a bow is being pulled. That triggers the tick count to be reset to the start and the shouldCauseReequipAnimation is not called for that at all.
