The term "zerg" is ambiguous to the point of near meaninglessness, as it can describe any amount of people in a given group from 12 - 100+, the level of organization of said group, and/or what that group is doing (aoe spam, sitting on BOs, etc.). I'd argue the term is improperly used in describing any of the aforementioned criteria, as such things can be named with more concise terms (premade, warforce, bombing, etc.), and instead is better suited to describe the feeling a player gets when he is attacked with overwhelming force and the sense of powerlessness it conveys to them (i.e. "zerged", a verb, not a noun).
Also, this popular sentiment I see thrown around all the time, that warband-play is "mindless"/"low to no skill" rubs me the wrong way. Would you also say that raiding is low-skill? The same concept applies in warband-play; getting 24 guys to operate as an effective fighting force can be frustrating at the best of times, not just in actually playing the game (practicing focus-fire, developing formations, learning volley-fire, etc.), but also in building a culture to ensure that such a force can be fielded in the long-term. This server knows very little of proper warband play, as the meta has been stagnate in lolcharging since its inception; so judging large-scale action on pugs is disingenuous.
If the Choppa pull is to remain, then we need friendly pulls in this game (akin to the one on the Holy Priest in World of Warcraft) in order for the receiving force to be able to counter it in some way. Right now, the Destro melee train has the ability to defeat Order groups even if the latter has near-perfect positioning. I can't tell you the number of times I'm with a group, Mara pulls someone, they successfully escape and we recover, only to have the Choppa lolpull one-two more people and we wipe because we spent the cooldowns/morales saving the first guy. It can be cast on the move (rendering its range effectively moot), its on a class already a staple of their melee train, its AoE and pulls multiple people, and it doesn't even need to be used to its full effect to be extremely efficient (1 pull is more than enough).
Everyone has a different conception of what "RvR" is supposed to be; some think they should be able to solo/duo-roam to their heart's content, others think anything less than a 24-man force and you might as well be playing WoW's arenas. Unfortunately, it seems like the solution Mythic came up with was trying to find compromise, instead of sticking with a singular vision; so we ended up with this RvR system halfway between DAoC and WoW.
