Six spots, close enough to optimize cleave damage and make it easier to stun them all at once. If you spread them out too much, the aura damage will certainly drive your healers oom.
You have people getting hit by two Marks of Frost at once. Either they are standing too close, or they are dropping debuff at the wrong time. They get a double tick, then explode and then probably get a double tick from the other pair. The explosion knocks you back a bit, so if no one moves fast enough, it's extra hit at 10+ stacks. It's probably a combination of all those things - people must keep an eye on the range check or they're doubling the damage they take.
You have people dying to Charge. It's a nasty spike damage that requires personal cooldowns, even a healing pot if you also have Frost on you. Fire dot does a ton of damage, charge hits hard and even initial dot application is painful. Also, at that point, if you have Mark of Frost and get charged, you can probably drop it if it keeps you alive. There's only a few seconds left so it won't kill anyone even if it jumps in some weird spot.
You have some healers going oom and yet they don't drink a mana pot. Maybe deciding that "it's already a wipe, it's not worth it", but it's terrible attitude. Non-Leytorrent mana pots are dirt cheap and you can't really afford to be stingy at this level.
No one uses any mana trinket, either. It's good for throughput, sure, but if you're useless for half of the fight, it might be worth to change? Admitedly, once you improve your Frost and Fire handling, you'll need a lot less healing, so messing with trinkets might not be needed at all.
