Having fun with new macros in 2v2 as holypala.

Mousewheel up: target my partner.
Mousewheel down: target myself.
Mouseovercast for repentance.
These three macros have made my arena experience much more fluid, as I no longer have to switch between me and my mate by clicking.
Try it!
Generally this is to prefer. The targeting macros can take some time getting used to.

The next step would be to not use a mouseover repentance, and instead run
/cast [@arena1] Repentance
That is, the Classic arena1,2,3 macros.

I myself run mwup and down for party 1 and 2, and a thumb button for target self.

Then for the arena 1,2,3 I have no modifier, shift, and ctl for the same button.

So for example 2 would be repentance arena1, shift+2 would be arena2 and ctrl+2 would be arena 3. No need to use the mouse at all for targeting, which saves even more time. Buuut it takes a few games to get used to.
/cast [@arena1, nomod, exists, nodead] Repentance
/cast [@arena2, mod:shift, exists, nodead] Repentance
/cast [@arena3, mod:ctrl, exists, nodead] Repentance

Similarily I highly recommend, in your case, to run shift mousewheel up and shift mousewheel down for dispel party 1 and dispel self.
/cast [@party1] Cleanse

I will probably run the same for Blessing of Protection for example, maybe at alt+mousewheel up/down and fast buttons for blessing of Sacrifice as well, whenever my paladin is maxlevel.
I realize the above post could have come off as 'elitist' or whatever, that was not my intention.

Good on you for starting to use macros to make the gameplay faster and more fluid! My post above is merely suggestions on further improvements, when you're comfortable with what you wrote yourself :)

Either way, I have been playing around with keybinds on my paladin, and have settled for the following:

mwup
Target Party1
mwdown
Target Party2
thumb button
target self

Shift modifiers for the above for cleanse party 1,2,self
ctrl modifiers for Freedom same as above
Alt modifiers for Blessing of Protection same as above

C for HoJ Arena1, shift+c for HoJ Arena2, Ctrl+c for HoJ arena 2

Other Thumb Button the mouse for Repentance Arena 1, shift- and ctrl-modifiers for arena 2 and 3

All other binds are "normal" binds, which require a target.

For PvE I'll run Clique and mouseovers instead.
Mate, these are great tips! I did not detect any "elitist" tone in your Writing. I'va saved this post to my bookmarks for when I need some macro inspiration! :)

Cheers for the answer! May the Light be with you, Paladin.
