The party is level 15 and the Rogue no longer bothers to scout ahead because, despite being optimized for stealth, the flying, silenced, invisible wizard with permanencied arcane sight is infinitely better at remaining hidden. The spotlight is on the wizard for the next 5 levels.
TLR (and I) find the above problematic, to say the least.
Coming from Shadowrun, I don't see the flying silenced invisible wizard as a problem since I always assume that so much (or in some cases, any magic) is the same as loudly announcing your presence. I simply assume that people long ago took some precautions against magic (Detect magic is a cantrip, after all, so items detecting magic are cheap), so in many cases the rogue is less detectable by avoiding magic, and by knowing his way around mundance options better than the wizard.
Mostly though I think that the spotlight stealing is not a rules problem, but a player problem. If you've got a player willing to outdo the rest of the party, then that's best dealt with by some talking between players, not by changing rules.
