I used to use proculas and have it announce in team chat when someone proc'ed.
I used it when I had a boomkin and it would say "eclipse" into chat and if I happened to see it I could change his spell casting bar ( /swapactionbar 2 ) . in the end, it was way too much work and I quit running with a boomkin and make him a healer instead ( and eventually removed proculas )

as for mages.... just cast 4 arcane blast and then arcane missles rinse repeat. mage needs to eat/drink all the damn time.

I like running with a frost mage in my team, it nerfs the mage DPS a little but I almost never have to stop and drink anymore due to the replenishment affect of the permanent pet.
