I pretty much agree with everything you mentioned in your list of 3.2 changes. As far as exorcism goes in a PvP situation I'd probably just use it while the target is stunned if I needed to use it.

It sucks that JoCom damage got dropped because 4x JoCom was a huge opener in a pvp situation since it always crit with stuns and incapcitates. Basically I would...

HoJ, 4x JoCom 1x JoR, 4x Crusader Strike 1x Shield of Righteouness, 5x Auto attack + several SoCom procs.

Basically killed anyone including very well geared tanks. For extremely well geared tanks I sometimes had to use a round of Divine Storm but still, that's a ton of burst right there. Hopefully JoCom crits are still something that hurts. ;(
