I just feel like I'm gonna see that my strength is sitting at 200 and even if I'm hitting OK it's gonna feel weak because I can see that I barely have any stats put into it... If that makes sense :/
It does. Make your build how you seem fit, and do small adjustments (tests) while doing it

I'm sorry, but that makes absolutely no sense. The return on stats is why we put points into them. If your return is poor after a certain number of points, what difference does it make if you had OVER 9000(!!) strength? People ask me all the time when they see my autos "What's your STR?!" I respond 200 and they say "What?! How is that possible?" Their next question is inevitably, "How do you have so much HP?" If you are looking for a build that makes sense with lots of auto damage, I recommend getting over the sticker shock of low STR.
If you said that having 68 damage was more important to you than the extra DEX or HP then I completely understand, but to have more STR for the sake of "feeling" that it is enough is just silly.
