This is primarily about 302, but I guess could apply to 317 also.
I know using CHANNEL is better than using CAST, but I was wondering a couple other things:
Are you better off channeling in guarded, or casting in offensive? I can hunt in offensive right now and not get touched, but am just wondering what I'll wanna be doing later on (rift/OTF/Temple) when things can hit you in offensive a lot, since that hard RT from CHANNEL will probably be a killer in those cases...unless the rumors are true that clerics are invincible in most high level areas, regardless of stance?
Also, what exactly do you get when you successfully infuse more mana into the spell besides a bigger mana cost? I haven't really noticed any extra damage either way on similar end rolls.
