Question about Astrologian and buffing in 8-man raid.

If you're getting bad luck with card draws and just can't get that spire/ewer, it's a greater dps loss to just hold onto that Balance/Arrow instead of using it. Personally, I wouldn't say to hold it for more than 2 draws tops, or that's potential dps you're just missing out on.

Incidentally, did they do something to the RNG? Last three days all I've Drawn are Balances and Arrows, and the rare Spear, literally nothing else. What gives?

You probably should, but any good AST knows not to only focus on aoe cards only, as RNG will take over and you can never get the cards you need. not all situations would call for aoe cards either, like mechanics that will cause dps to not be able to stay on bosses for extended periods of time, or healing becoming to much for you to benefit from it, you choose based on situations.

No, they didn't as far i know the only change they did was so you don't shuffle the same card. but the RNG is still the same, as i'll get nothing but ewer and spire cards for 5 minutes straight. it's just RNG letting you know it still rules you.
