Our 10m guild did heroic stone guard for the first time this week. To provide some context, we're 6/6 MV and 2/6 HOF, however we've only just started HMs since we are behind on progression since we're a new guild as of this expansion. It takes us ~1hr15m to clear MV on normal.
This week the pattern was jade, jasper, cobalt. After nearly 40 attempts, we got him to 3% on our best attempt.
The biggest problem we faced was all of us getting chained early, with no jasper petrification. This seems to RNG into this problem a *lot*. Which in turn meant:
* Cobalt mines started filling up the room, since it's harder to break mines while chained (with deterrence or during cobalt petrification)
* Tiles stop getting painted, or painting slows down significantly ( less DPS and healer mana begins to get soaked up)
Now, I'm not saying SG is unbeatable if RNGed into this position, but it makes the encounter a great deal harder.
So, it leads me to the question... are there any tips for this combination?
On a similar note, is there any way to control petrifications? AFAIK, there isn't, but if there was it would trivialize some of the fight.
