Not much to add to what you already said.

For someone supposedly so super strong Jiemma was dealt with far too fast. If Mashima didn't want to spend too many pages on that fight, he could have made it continue off screen while focussing on Natsu and Gray, occasionally show a frame or two of them until he comes back to them for the conclusion.

On the other hand maybe it is better this way, since we already have to many things going in parallel it's hard to keep track. Erza vs. Kyouka, Makarov at Lumen, Acnologia vs. Igneel, Natsu+Gray vs. Mard... and that's just the most immediate stuff that's happening, all at the same time.

But then again it'd also suck if there were only one or two fights going on while everyone else just stands around and watches or talks... there doesn't seem to be a perfect option to get out of this mess Mashima wrote himself into.
