The pace is reckless and getting us killed

The bunch of us just finished a Naxx10 to celebrate Z's priest hitting 80, and also to gear up my rogue for reasons that won't be discussed here. Along the way, we've had someone in our group who, despite having been to Naxx countless times, was still clueless about the various aspects (tank, DPS, heal) of some boss fights apart from what he was used to playing. This brings me to the point that the people in those progression guilds striving for world first, are so good, that they even bother to familiarise themselves with the other aspects of a boss fight, other than just knowing their job scope alone. It is these people that are really really good. Hats off to them!

Anyway, we cleared the Plague Quarter first, and was stuck for quite awhile at the gauntlet before Loatheb, due to some... reasons. Other than that, it was fine. Then we headed to the Arachnid Quarter, and, other than a few mishaps, managed to kill everything. Just before our Maexxna kill, however, we lost our offtank to real life issues, and B replaced him with a prot pally who seemed competent enough. Proceeding into the Military Quarter, and the trash immediately after Instructor, we lost our main tank to a dinner appointment, and had to replace him too. The pally now pulls two packs of weapons (a total of 4), which we handle okay. Sticking to the left wall, our new tank, the druid, pulls two more that I marked before hand (I had a total of 6 marked at this point), and to the horror of horrors, the pally uses his Avenger's Shield to pull 2 more, and naturally his shield jumps into another pack, so we had a total of 6 weapons on us. Needless to say, we wiped. This is what the pally said in raid chat afterward:

I mean, we're moving along at a very slow pace by my standards, and you pull an extra 4 mobs, AND you spring this on us? -100 points for the mispull, -3900 points for that remark. Gothik was ok, but the trash on the way to 4HM was marked by many many Misdirections from K, and many many Tricks of the Trade from me and B, because it seemed that both tanks' threat were very very low. Surprisingly, 4HM went fairly well too. However...

We now come to the last wing, the Construct Quarter. At this point, I start noticing that the paladin is pulling with his taunt, Hand of Reckoning (WHAT!?). Does this mean he knows he was at fault earlier, and is afraid to use his Avenger's Shield to pull, lest he overpull?? Patchwerk and Gluth seemed ok, but again, there was an overpull in the corridor leading to Thaddius' room with all the pats. We had 2 of the big pats that do a ground slam thing, and a shade. The best part? After these 3 mobs, said pally planted a Fish Feast on the ground, smack in the middle of the corridor. Naturally, being curious creatures, the second shade and the pack of small jumping mobs came to visit, and B died almost instantly. Well done, pally, well done.

Everything seemed fine up until... Kel'Thuzad. In phase one, said pally went to melee a Soul Weaver. FYI, thats the banshee type mob that does large Shadow AoE damage to people on a melee hit. So, as you can guess, we wiped again. The pally, claimed it was "the wife waking up" that distracted him, and so he "forgot" and went to "hit skull on instinct". Bullshit. He died twice to the void zone on the subsequent attempt (and kill). Pure bullshit.

Conclusion: DO NOT emulate -4000 points in any way, manner, or fashion. We are still laughing at him to this day.
