Not intentionally- in our recent run through RttToEE, our Rogue died. It fell on my Ftr/Rgr/SpecWiz: Div/Spellsword to pick up the slack on trapfinding...which went just fine. He not only had spells he could use, he even had the skills to do the job, up to a point. He had high ranks in most of the skills, but by rule, some things can only be done by a Rogue.
And the Barbarian was pretty good at opening the otherwise unopenable.
IOW, things went OK.
Eventually, though, we got the Rogue brought back. We did fine without him, but it went much more smoothly and efficiently with him back. It meant that we didn't have to expend spells or risk the big meatshield to do the Rogue's job.
