I really don't see any real benefit to strength past 11 or 13 on this class. Combat maneuvers still benefit from DEX, not just STR, for your weapon, and you can use heavy armor regardless as it comes with the class. The bonus to your damage from STR will be relatively small compared to the bonuses you already have since you don't get it until level 10. Could someone describe what benefits you get from a STR build on this class, because people keep referencing a STR build being more defensive and I just don't see why that would be the case in any significant way.

Like Owen said, this class is not built with STR in mind as any kind of key stat.

My primary issue is that it quickly becomes hard to justify even buying a weapon unless you absolutely need the special property/crit effect/fusion that it provides as your entropic strike damage increases on its own. If I can just punch for the same damage, it feels unfair to make the Vanguard spend a bunch of credits while only getting a marginal benefit.
