Nevermind the fact that Yoshida himself said they want to take the time to consider player feedback about the beta and not make the same mistake this time around >.>

That being said, regarding the UI, I can't feel but this is lazyness on the part of SE. SWTOR has an option to scale UI. If SE knows it's being requested, or thinks it may be useful to some players, there is NO reason why they shouldn't include this themselves instead of relying on an add-on. Hopefully this isn't a sign of the future- "oh, someone can just fix it with an add-on"
