I'm not sure about the rest of my raid back then, but for Brutallus we did have a dedicated melee group where everyone was LW with deayed /w macro that told the next person to use their drums, that group also got every BL available (you were allowed to swap ppl between groups back then) it was also the only encounter where shamans were required to totem twist. Wasn't really needed anywhere else. As far as I'm aware, there wasn't any real obsession with parses back then though, so as long as the boss died, no one was really sweating it.
