What drives a poor reputation for the Rogue class?

[Psyren]

I mean, by the time a rogue is fighting an Ancient Red Dragon they should have Slippery Mind, if not Stroke of Luck. Even the far weaker 2014 versions will help a lot here. And while the DMG doesn't prescribe specific magic items, it does say you're expected to have some by that point, and hopefully they'll be helpful ones - not just, like, a handy haversack or portable hole to store all their mundane gear more easily. (Though I suppose Handy Haversack + Portable Hole could be a way for that rogue to quickly deal with a dragon )
