Those traps are actually invisible unless you got a rogue in the party who can also disarm them.
I got my rings yesterday (just friendly) and it really wasn't that bad albeit not very entertaining.

The Wards are indeed not much fun at all but you can always run out and back into the starting room when you got a trap triggered since they evade.

I usually got about 280 rep per run and then waited a few minutes for the mobs to reset.
