I've observed a 40% wipe rate with the A/B/C method. That's not less risk. That's more risk. You and people who agree with you can keep calling it less risk, but it's just not. A/B/C is the risky choice on the NA datacenters. Maybe it's different on the JP datacenters like someone said above, but on Aether, it's a 40% wipe rate. Or was back when anyone would be reckless enough to try it - no one does anymore on Aether. At least, no one has tried in the past several dozen runs I've done. Only once did someone whine loudly and repeatedly about the all-DPS method despite everyone else wanting to do it that way. We agreed to do it the A/B/C way, and then all the DPS ran in anyway, because this is a game and people are free to play it the way they want to without others telling them what to do. FYI, we didn't wipe. We cleared it easy.
Cerby auto-wipes the raid if you take too long. He gets stacks of Haste over time, and if you wait too long, gets a massive Damage Up buff that makes him start one-shotting people. Saying "there's always backup" makes no sense to me. What do you do, send in a second team when the first wipes? Does the MT (only one left outside) pick up the Wolfsbanes and Cerby, or do you wait to revive the whole other team first so the other tank (the one with weakness who died inside of Cerby) can tank all three Wolfsbanes? Do you have two healers handle the damage from all three wolfsbanes and cerby while the other two living healers go inside? How do you do all that without Cerby hitting enrage mode? What do you do if the team inside doesn't die, but just does too little damage (maybe their DPS all died trying to get in)? At what point do you say "the team inside needs backup, so let's switch to the All-DPS method?" How is that any different from just starting there, and why not just start there if you're going to rely on backup?
You said it yourself that heals and tanks aren't needed inside, so why do you tell all of B to go inside? If you're doing the A/B/C method, why not just send in the 5 DPS from B? Do you need the extra speed of having that extra DPS from the tank and healers? If so, a sixth DPS from another group would do as much (if not more) than those three members of team B combined, so why not send in B's DPS + 1 and stay outside to heal/tank the Wolfsbanes? If five wasn't enough so you needed that extra DPS from a sixth, then what if one of the six dies getting in? Send in a seventh just to be safe. Keep going with that logic train and you get the all-DPS method.
Saying you did it on B and didn't wipe, so no one wipes with the A/B/C method, is just wrong. Back when everyone used that method, we never wiped when I was on team B because I knew what to do and explained things to the party and enough listened so the unknowns weren't killed and the DPS made it in without dying. But, when I wasn't on B, wipe after wipe despite saying the same things in Alliance chat.
Also, to the people who say that advocates of the all-dps method are only DPS who want to get in the belly, I call BS. I prefer tanking WoD (though tank queues being horrible for WoD (plot twist!), I often queue as DPS for the insta-queue). I love calling OT and tanking the Wolfsbanes (or two of them if the other OT is paying attention and grabs the third) while the DPS are inside, just like I love being OT for the 5-headed-dragon fight and running around to handle mechanics so DPS don't have to (grabbing all the fire tethers, standing in all the poison, stacking with the purple marker, possibly covering them with Sentinel up, etc). Being an OT on a raid like this means you get to handle mechanics, but sometimes, no one is willing to be an OT and instead spend the whole fight fighting over MT. Sending a tank inside on Cerby requires all three tanks to be good for you to clear it. Not sending in a tank only requires two tanks to be good to clear it. That vastly improves the odds right there.
I'm not advocating that everyone should do the all-DPS method. While I find it to be less risky, you should play how you want to. I'm just saying that if the majority of the raid wants to do it one way (ie: all DPS in), get over it. People can and should play how they want to. It's a valid method (more valid than A/B/C, if anything) and saying one is "doing the fight the way it was intended" is just wrong. If a full team was supposed to be in the belly, damage from the Unknowns would be significantly higher to necessitate tanks/healers being in there, but damage in there is laughable (unless you're soloing it). If two full teams of DPS were supposed to be outside, then the adds outside would be strong enough that a single tank couldn't hold two of them, but a single tank can easily hold all three. Or, there'd be a DPS check outside as well as inside, but there isn't. Or, the number of people inside would be strictly limited, but it isn't (it might be limited to some number, but that number is much higher than 5, which is a single team's DPS count). Of course, if it was intended that only DPS go in and all DPS go in, there would be no adds in the stomach giving some small purpose to heals/tanks if everyone is horribly undergeared, and there would be no adds outside meaning there's no reason for DPS to stay outside. Neither is intended and both are intended, because SE wants you to play the way that works for you, and they've said in the past that they find it really interesting to see how people decide to handle the mechanics and how they differ from their expectations.
