(just as a note if your took jack of all trades to not use it, i would suggest a different feat at level up) .

except for indulgence who is aged 2+party members years.
I couldn't disagree more, and the snarky suggestion to retrain is unnecessary. I chose the feat for a reason, and the reason remains valid. For warlord Insight and perception are untrained, and so the feat gives a bonus to the passive insight/perception, which you presumably rolled for each of us when we approached the trapped room, and which as it turned out we happened all to fail. If you ever called for an acrobatics roll, or a knowledge roll, or any other specific roll, then Indulgence is 10% more likely to succeed. This is, or at least should be, a great benefit.
Where it doesn't help is in skill challenges, as here. An untrained skill is going to be at +6 to +8 in this case, even with the feat, which is less than the trained skills, and where she can expect 2 failures for every success (2:1). Given that the penalty comes at 3 failures, and the victory at 12 (4:1), the imbalance (8:1) is hugely disproportionate to any effort put in.
Look at the liabilities Indulgence suffered: *because she tried*, she is aged an *extra* 4-5 years. Not trying in this case would have been much more advantageous. As it stands, as my IC post demonstrated, is that it is not worth trying to avoid these things with suboptimal skills. Everyone has now aged 6 years, except for indulgence who has aged 10 or 11 (depending on what you mean by 2+part members), and we are less than halfway to success.
