I know y'all don't wanna hear this

I know you don't wanna hear this, but you are wrong. It is really that simple.
Wall-to-wall pulls are tactically stupid, does not shave more than a few seconds off a run, and really serves little practical purpose other than giving wannabe-elitists something to complain about when other people don't do w2w pulls.
It is especially silly in low-level leveling dungeons when many classes don't even have AoE attacks yet.

If wall-to-wall pulls only shave off a few seconds, then DPS must be extraordinarily low. Before I did w2w pulls (back in ARR), I remember ARR leveling dungeons taking on average 30-40 minutes (maybe more). Now it's typically 16 minutes or less for all dungeons. For low level dungeons, yes, mostly just tanks have AoE but it's still AoE.
