What is the point to purge and Dispel?

[Maxion]

Also dont forget that purge and dispel magic only removes magic type buff/debuffs. the other types you need other ways to remove, if you want to remove them anyway.

Stop casting in my priest macro with a targetparty targeting method? Man, that makes my head hurt.

So, press it once and a) you aren't sure which party member gets targeted and b) you might cancel a healing spell.

Press it enough to cycle through your group and you basically have to wait, what, four global cooldowns before you could resume healing and you'd have to time the key pressing correctly?

I guess what I was talking about was dispeling or purging the mob and not party members. You know, to have an "always on" attempt to dispel beneficial buffs the mob may have up. (i.e., Paletress' Renew)
