Pretty much, I think people tend to confuse rushed endings with padded content, no amount of extra episodes/comics is going to help when it’s obvious the reason the ending had so little time put towards it is because too much was put on the unimportant stuff meant to make the content entertaining and not enough on the actual plot, which
used to be a balancing act the staff was able to pull off.
If somehow this turned out to be a 3-part episode, the problem still wouldn’t be solved since all the extra time would likely had been placed on the Tirek and Flim & Flam timelines, along with a few new ones. They could’ve sacrificed whole minutes on the Sombra, Chrysalis and Nightmare Moon parts, but they didn’t because their focus was on giving each villain their spotlight from the start, not on making a meaningful ending.
This is the S4 finale’s duel with Tirek drawn out to 30 minutes or so: no advancement on the actual plot other than introducing the (Way too convenient) arbitrary “Every use of the scroll leads to a worse future”, which brings a whole lot of issues on it’s own, but hey! Cool stuff! That’ll make like half the viewers ignore the obvious plot holes and horrendous ending!
