Common automatic gear swap examples

[Gello]

It looks like events may make it into ItemRack 2.x before the heat death of the universe. I'm looking for some examples where gear changing automatically is useful. The list so far:

When mounted (*)
When in a BG or arena
When in battle/defensive/berserker stance
When stealthed
When in shadowform
When in caster/bear/cat/tree/boomkin/etc druid form
When in ghostwolf form
When in a city
When drinking

Any others? Mages no longer swap for evocation I take it?

There will be the ability to script your own event so anything not listed is still possible if you can script it. I'm just looking for stuff to populate a premade list, and maybe forming a new event category if I've missed an obvious use.

(*) edit: mount event may be moot when/if riding crop/carrot/etc become mount enchants
