Off the top of my head: the focus on skills rather than combat training or intense bursts of power. Whether Social climbing, sneaking, actual climbing, knowing stuff, the Rogue has not only a broader skill base, but a much more capable one.So what of that can't be achieve by role playing fighter or barbarian as thug? What does the Rogue class offer as Strength based design like this that makes it the choice for this subclass?
Why play a dex-based fighter? Does that not step on toes?Again, that's why I keep referring to the rogue class as a group of features. What detracts from this if the athletic criminal is based on the barbarian or fighter features? Why rogue? Does this not also step on the toes of those classes since they exist to fill that void? Being a criminal is not class specific and could be applied to any class.

- Presumably you pick Fighter rather than Rogue for the combat prowess of the base class, in the same way a strength-based rogue picked rogue due to the skill capabilities of the base rogue chassis.
There is a distinction between not having a high stat, and dumping a stat. A lot of barbarians, and a few fighters I've seen have 12-14 Dex. Even for fighters in heavy armour, Dex is good for a lot of reasons other than AC.So they are taking a dex tax due to insufficient armor? I mean I don't generally see strength Barbarians or Fighters with high dex too. What is it that provokes this design as a Rogue with a dex tax instead of Fighter or Barbarian without one? Even if we disregard the skills not needing dex, is their anything that supports strength like Barbarians rage?
There is no "even" about disregarding skills not needing Dex. Skills commonly paired with Dex are in the minority in the rogue's list. In terms of directly boosting Strength-based ability, a rogue's use of Athletics, whether for climbing, running, and other typical rogue uses, or for shoving people around in combat are directly supported by several features of the Rogue class.
They're much better in combat, being tougher, less restricted, and having greater capabilities.What makes this good as a rogue build. Is it just "because" and if so does that mean its stuck on this idea of the rogue feature package name?
1. There is nothing in rules that prevents a fighter or Barbarian from being a strength based criminal thug with these features.What makes them better on even as good as a rogue?
But they're nowhere near as good when it comes to versatility out of combat and skill use. - I'm guessing it depends on what you mean by "better".
Because you want to play a tricky, skillful character who gets by in combat through dirty fighting rather than being an outright combat monster.2. If they are not as better on a rogue why is it important mechanically or in role play to tie this subclass to rogue features?
