I totally agree
(and relate as someone who is also not a local or AP holder),
BUT...
-i love a good Devil's Advocate-
By that logic,
IF it wouldn't make the situation worse in any way, why hasn't Universal done it yet?
The fact that they haven't kinda points to the opposite narrative and i think the overall throughput of the rides in the parks is that very reason. We harp on capacity all the time in this forum, we have to imagine that something around even as little as 10% of those APers would actually end up impacting some lines negatively, if not more. It's wishful thinking to say they wouldn't but call it calculated human error or pure spontaneity at play, but the fact that Universal hasn't approved AP's for EPIC means that they do not currently think the juice is worth the squeeze for some systemic or economical reason and they're leaving that money on the table for that reason.
The general consensus of not just this thread but the entire theme park community is that they're not going to add APs to EPIC because they're worried the park would not be able to handle the capacity increase in more than one way or another. Just because something looks easy right now doesn't suddenly mean it would be totally manageable with an added 100-1,000 more people to consider. Restaurants that look relatively open and easy to walk into right now suddenly have waits, those people who would have went there now go somewhere else, and the overall flow of the park takes a hit.
Exactly what
@HalfGlass said - MORE BODIES is not going to help overall guest satisfaction in any way.
IMO we will only see APs added when there is literally MORE in the park to do, which echoes the sentiments of many in this thread. It might be ONE ride, it might be TWO, but when they add more to the park, i think whatever balancing act they're playing might finally have some leeway to pull that trigger more effectively.
