True, it is mostly about dps. Most of the new people who use low dps weapons or healing beams only do so one or a few times until they find out about the pulsar/wolfhound combo and the reasons for the technique.
That was something the intermission between between the upper level fight and the monkey in the basement breaking out before the timers were put in was good for. It allowed the experienced people to brief the players new to the event on the best way to win it along with the time to actually change their loadout to something appropriate.
Lockbreaking (which is probably done as much by experienced players trolling as it is done by new players) is a disadvantage for a lot of reasons. Something that should be obvious but apparently is not to some people is that the lockbreakers have to expend a lot of ammunition to break them and so are short on it in the critical early part of the encounter.
It is especially bad when the lockbreakers are spread all around the room since if everyone is in the "firing squad" formation out of sight behind the WM the monkey will stand up, stretch-and-roar, then pause a moment before turning around and attacking. If someone is in his view he will often as not cut the stretch short and go right for the attack right away, roaring as he attacks. Those few extra seconds of massed fire directly into the monkey's back make a tremendous difference in the outcome.
