All AO2 maps used to be rushed in 5-bear or 4 bear 1 paladin teams back when 45 was the cap. Maps 4, 5 and Plasma Pyramid were particularly popular. Imagine skipping all djins in Chariots and trailing them behind you all the way to the boss and having 6 djins pounding on you while you were killing boss. And this was before the rebalance so we all had half the health we have now (although it's true that level 45 gear also had dodge comparable to current 55 pinks). And no, we didn't use any elixirs.
Regarding the boss level, I'm kind of glad there isn't one in BS. Each BS map is interesting in its own way and this way people do them all. What's the point of having several maps that nobody plays except once to unlock the final map, like it used to be with AO3 (and the only reason people also played map 3 there was because of what was probably an error in the VL Tpaxx loot table). At least in AO2 Plasma Pyramid didn't give rares, so people played/rushed all maps.
