Learning how to properly play AST

[Rongway]

So far the healing is fine but maybe that changes later?

It does change...it gets better. With Synastry, if you heal someone other than the synaster, the total potency of Benefic is 400 * 1.2 * 1.4 = 672; you're basically splitting a cheaper Benefic II unevenly between two people. And then as mentioned previously, once you have Collective Unconscious, you have the option to put up a triple regen that heals almost as much as a Benefic every three seconds.

Stuff about cards

More stuff about cards

It's nice that you took the time to make macros, but it's not really necessary. If people are so focused on what they're doing that they don't notice the buff flytext or buff panel, they won't notice the /p notification (or worse, notice it and get distracted).

For the people who do notice, behavior change while buffed will be minimal, with the exception of a decently timed Spear, where someone might decide to activate a support ability a few seconds earlier than he would have otherwise. And aside from that, most people will just do what they would have been doing anyway; so the only person whose behavior is significantly dictated by the cards is the AST using them.

As for Royal Road and Shuffle, sure, some cards aren't as desirable as others, but keep in mind that if you Shuffle-cancel or Royal Road-Royal Road or Draw-cancel too often, you're losing a lot of potential buff-person-seconds. If there isn't a very specific, difficult phase that you're saving a very specific combo for, you might as well just use some of the cards that you initially want to throw away, just to avoid going two minutes without actually playing any cards at all.
