You speak truth, sir. I played on a Classic team that produced 4 or 5 Grand Marshals, and quite a lot of Marshals and Field Marshals. And a whole slew of the lower ranks. We had a backlist of people waiting every night to join if one of the core group needed to take a break. We did also raid and virtually everyone had t2, 2.5 or t3 or a mix of that, some wore their Field/Grand Marshal gear, especially the weapons because those were pretty good stat-wise.
People think all we did was roflstomp pugs, but it isn't so. Because our bench was so deep, we mostly played Basin as we could take 15 instead of only 10 in WSG. Before battlegroups, we were mostly running up against pre-made teams, I'd say 60-70 percent of the time. Those fights we deemed a success if we 3 capped and won, and a good success if we 4 capped and held on for the win. Usually against a pre-made our goal was to take and hold 4 bases and harass them at the 5th.
Pugs... when we did get a pug group, we of course would 5 cap them and farm them at their spawn point GY. And we often waited 20-30 minutes in queue between matches. Our goal, of course, was to win quickly so we could requeue, so we were pretty happy when we stumbled into a pug team. Matches against pug teams only took 5 minutes to win if we 5 capped within the first 1 minute of the match start, which we usually did.
The addition of battlegroups changed things of course, most significantly we had shorter queue times which was nice. And occasionally to break the Basin monotony, we would queue Alterac Valley, tell the 25 plebes in there to follow us, and roflstomp the place because we were on a chat server, had a geared tank and healers, and were organized enough to wipe the map clean quickly.
Good times. I was hoping that the RBG system would bring some of that feeling back, but the RBG community is gross and toxic and Blizzard hasn't helped it with how badly they have handled balance, MMR, and virtually everything related to the entire ecosystem.
