Hey guys.

I started leveling AST some time ago. Being lvl 52 now I still have few unanswered questions and I can't find updated info anywhere.

First one would be about Royal Road. 3 DPS cards and Bole all seem too good to burn them in 4-mans, so I assume I generally don't use it outside of AoE buff?
What about 8-mans? Do I ever use Balance, Arrow or Spear on single target?
Are duration and potency buffs ever worth it?

Another problem I experienced today is 2 AST in 8-man instance. How do I go about buffs overwriting? Prepare AoE Balance (or maybe any of the 3 cards is fine now?) and wait until other AST's buffs fall off? Ofc I'm talking about PUGs with limited or no communication.

And while I'm not there yet, are any cards that should be always converted with Minor Arcana?
