Kingsmarch Letdown

Hey, love the League so far, flows really well.

However, I felt very let down when the upgrade action in Kingsmarch did not come with the nifty animations advertised in the League-Trailer.
Can't be the strain on hardware resources, because we know where PoE goes in that regard.

Building animations, especially slow and more detailed ones, have always been one of the staples that drew people in to early RTSs and Economy Sims. From the the ones in C&C and even better in in Earth 2050 (specifically the ED-faction). Some games may take shortcuts but the plain "pop it in" is usually something we see mostly in mobile games nowadays.
When done right, these types of animations can have an almost hypnotic, relaxing and rewarding effect, as everything is slowly coming together. It's a pity this is missing now.

You had these things ready in the trailer. What was the reason to not implement them?

Personally, I would have been fine with everything that being there instantly but taking its time to be finished. The ship takes its time, the upgrade on some building can take just as long.
Or alternatively just watch the town slowly grow while talking with friends in the guild.
