That's fine. There's plenty of data showing an AST in Diurnal with a SCH is a good combo. And you're right, stacking shields wouldn't be much of a problem until you start trying to anticipate who/when the SCH will shield. A macro could help with this, but it'd be pretty unnecessary -- relegated to when partnered with an AST who wanted to run Noct. Teamspeak and other tools would definitely help, as it doesn't take a whole lot of effort to say "Succor" or "shields" etc.
I don't use vote kick, so I didn't know that. Most of the times when vote kick prompts in my groups, it's usually been well after the first boss of a dungeon/tower run. Also, it has nothing to do with intelligence and everything to do with attitude. Some people are just unwilling to put up with the tiniest things. Imagine a group of buddies who queue up for trials, they've got a SCH and the AST their paired with either makes the mistake of going Noct or consciously chose Noct. Your statement was you'd kick them. Not talk them out of it, you'd flat out kick them. You presented an extreme reaction with no other details. You just need a majority rule to kick someone, and you don't get a whole lot of options to explain why you're kicking someone. Choose AFK and anyone who's not paying attention to what the healers are doing might think, "What? AFK? Can't have that."
XIV might have a pretty healthy community compared to some other MMOs, but that doesn't mean jerk players don't exist (or that they travel alone, as like attracts like). So, not assuming you're a nice, or patient, person your statement alone reads as a insta-kick.
Now that I do know about the 5min window, I suppose insta-kick will refer to the first moment the vote kick function can be used. 5min is plenty of time to correct any errors you're making, or talk with your party, and for them to decide if they want you out or not.
Also, no reason to use sorry. There's nothing to be sorry about. I'm certainly not going to feel bad about not having the knowledge I do now. But I'm going to keep thinking things through with what information I have, and post accordingly. Not like I can't be corrected. Heaven forbid I recognize I can be wrong :O
Doesn't stop me from being interested in how the two classes would interact. Like, would the AST still pop Synastry when massive healing needs to happen on one person, or would they pop it for the healing boost so that they could bring everyone else back up quicker, before going back to healing single targets? Does their Synastry+Essential Dignity combo become a better choice than Lustrate for a tank (maybe? Don't remember if they confirmed healing Synastry target was a bug or not, because a tank sitting at 1% from HG/Hlmg/WU might want the 1250 potency + 40%)? Two 400 potencies + 300 potency, and then the entire SCH kit plus whatever the AST brings... It at the very least sounds interesting.
The point would be letting AST players try to be outside the box and maybe find other situations they might not come across unless they found themselves in it. SCH had to learn b/c there was no choice in the matter. AST can at least look at what happened with SCH and work from there.
