Umbran said:If you have three people playing rogues, they will tend to overlap abilities quite a lot. If the players are not careful to really differentiate their characters, it will be difficult for individuals to really shine, and there will be many things they collectively won't be able to handle.
I don't think that bears out. Not every rogue is created equal -- different ability scores, different equipment, different subclasses, different backgrounds...there's a LOT of variety even if some of those things are the same in several party members. And there's no reason that this group couldn't go on any adventure that anyone else could go on. They might need to play it a bit different (a little more spy-bluff-sneakaport than kick-in-the-door), but there's no limit on their adventuring potential.
Yeah, they don't have a dedicated healer, or a dedicated defender, but you don't need a dedicated healer or defender to play a game of 5e. A couple of healing potions and a reasonable sense of when you need to rest and when to retreat, and you'll be fine. You might have to be cautious, but being cautious is the name of the rogue's game anyway.

You could do the same thing in 4e, of course, the design just wasn't pointed in that direction. A party of rogues would be a bit more homogenous and a bit less well-rounded than a party of rogues is in 5e.
