How to deal with non contributing players

[OurMom]

1-50, you can solo/duo/trio just fine at 50/50, 50-90 you can typically solo/duo/trio if already at 99/99 or near it. 90-100 is harder without the pomanders, and if your party won't open the chests, then the boss is just harder.

Me and a buddy duo'd to 150, again if you're struggling pre 150, that's a player problem. Also not opening chests at all is not what most parties do, people just dont like it when someone goes out of the way to get chests even when the portal is up. Most people grab coffers on the way no problem.

I rarely see any party head straight to the teleport before it's unlocked

I don't really see this happening either.
