How can we save dungeons and varient.

no. this is the optimal dungeon design

you will run it every other day in expert coin flip roulette and be happy, until the next one comes out 5 months later.

Yeah this is actually the optimal dungeon design. Even if you added extra side paths, no one would take them. The community forced the current dungeon design by just beelining it for the most efficient path every time.
Constant fights about how much to pull? Game decides for you and you just pull 2 packs and a wall stops you from pulling more.
The constant path of least resistance taking just cements the idea there's only 1 true path and then there's the one noobs take and get flamed, so just remove the other ones to prevent the flame.
