So Second Coil has been destroyed

[Felessan]

with t1-5 it was "easy" to get over because most of it was largely unchanged. t6 and t7 however, have been made easier than t1(not my opinion).

I went to DF parties for T7 for my amusement. Out of 4 parties and about 15 tries we cleared T7 once. It's much easier than before, but nowhere near current T1 in terms of difficulty.
You need to do something with Renauds as unfreezed pack of 4 will kill your healers just as they did it before. You need to be carefull with voice/shrieks as unfortunate petrification will cause wipe, especially if tanks/healers is be petrified. You need to dispel otherwise people drop like a flies from venomous tail. You need to focus adds (and half of people tends to ignore this) or offtank dies and then everyone else.
It's more a story of a bad parties than a good one, but still it clearly shows that even with actual gear this content cannot be facerolled by any casual group, you need a little bit of understanding anyway.

t7 facing away barely matters anymore, except for avoiding giving the boss stacks. renauds hit for about the same that regen tics for (4-500) so just let healers grab em or let them wander around.

Raid-wide shriek still will cause wipe more often than not and many misfired voices have very serious consequences, Yes, it's not that fatal as it was before, but far from ignoring it completely.
Do you know what happens when someone decides to stone tank and melee on first adds phase? they create a very nice composition while second add just kills all healers and proceed wiping a raid.
