Should developers design raids around Latency?

Over the last couple weeks I've been having fun learning the raid encounters in Wrath of the Lich King. I've mostly been absent from the raid scene since the Karazhan hump broke up a couple of my guilds. However, I was tempted back after I kept hearing how casual the new raids were in the expansion. So far it seems true and I've found both the 10-man and 25- man versions a lot of fun. The fights I especially like are the ones that are more involved and require coordinated movements. I think my favorite is the DDR like strategy required for Heigan, but Thaddeus and Grobulus are also fun. However, I've noticed that these fights can be inherently harder on the 25-man versions because of random latency issues.

The effort of coordinating twenty-five players is always going to be harder then coordinating ten players, but that's not the only reason that the heroic raids are more difficult. Increasing a raid to twenty-five players also makes a raid more vulnerable to one person with latency issues causing a wipe. This is especially true on Thaddues where one person with the wrong polarity at the wrong spot can kill everyone. Sometimes just a second delay on a player's screen is all it takes. If that weren't the case then the frogger slimes after Patchwerk wouldn't claim so many people. I shudder to think how Naxx must have been back when it required a raid of forty players all having good latency.

I guess this is why back in the day Naxx was for hardcore raiders only. Hardcore raiders not only had the free time to devote to these encounters, but they also had stable Internet connections. Guilds that got to Naxx back when it was forty man had to kick anyone who was slow on coordinated movement encounters. The worst part is that it's very tricky to tell if a player was being slow because of skill or if they simply had a small bit of lag on their connection. Designing around latency has always been an issue with MMOs and limited their design. The reason auto-attacks and hot buttons are used by everyone is because real time combat is vulnerable to lag. Just look at how useless combos were in Age of Conan's PvP combat.

The developers originally designed fights like Thaddeus because Naxx was supposed to be for the most hardcore raiders. This meant the developers could assume everyone had perfect Internet connections. Now though with raiding being more casual it's probably irresponsible to design encounters like it. Oh, I admit the idea of the polarity shift mechanic is genius especially on a Frankenstein like monster. However, it shouldn't kill everyone in the raid if someone has a connection that lags out every once and awhile. At most latency issues should kill the one person in the raid who had them. This means that a casual guild only has to make sure the main tank and his healer has ironclad connections. If Blizzard is serious about keeping raid encounters more casual then they might want to take into account that all cable modem connections are not created equal.
