Am I the only one who feels that zerging has nothing to do with the 5-man caps for AOE/buffs? Maybe my server is different, but over here, we have basically three kinds of groups: roamers, guild zergs, and pub zergs.
Roamers cap a camp or maybe even a tower every now and then, skirmish with other roaming groups, and get wiped by zergs. Not a lot of people roam because there’s not much reward for it (can’t cap big things or as fast as a zerg), and if you really want to fight in small groups, SPvP is a better place to do that.
Guild zergs do two things: fight other zergs, and cap everything from camps to stonemist. And the latter is usually just a way to get to the former. I would call it “riding the bag train,” as bags are what they’re concerned with for the most part.
Last, and anything but least, are the pub zergs. By far most players on my server fall into this category. They do one thing, and one thing only—follow the public commanders who drive the karma train. Basically, it’s flip camps, flip towers, flip keeps, etc., as long as we don’t ever upgrade them, because that would slow down the karma gain. The whole idea of PPT is lost as the reward for defending anything in WvW is less karma (as opposed to being on the karma train) and less money/loot (upgrades aren’t free, you aren’t completing as many events, and not killing as many champions). Naturally, the bigger the karma train, the more desirable it is to be on, as the PvD goes faster (you have more total supply to build siege, and more people to DPS the door down after siege is built).
Basically, the reward for roaming in a small group just isn’t there. The band-aid “fix” (i.e. Righteous Indignation) just serves to redirect or slightly slow the karma train, and not to encourage roaming.
