I get that you want to know what people think of the update, though I don't think it needs to be mandatory that people explain why. Their opinion is enough to say that they like/dislike it.
This isn't really a spot to give reasons to why you do or don't like it, forming a suggestion in the same message.
I myself, love the new update, but there are a few bits which I don't like.
Although the new blocks are something to get used tom I think it was a good call & brings more colour into the game itself. The new generator mechanic isn't really appreciated for what it actually prevents (gen hogs), yet people freak out over a fraction of a second being wasted by the pick-up time.
The generator animation speaks for itself: Original, slick and informative.
Coloured armor: I love it. Simple as that.
New maps are always welcome, as it doesn't matter if few people don't like it. Others will definitely appreciate it & play on it, so it's definitely not going to waste.
Punch bow increase was long overdue, and Ender pearls are a life saver when it's Normal mode.
I don't think there's much else to mention, so I'll leave it at that.
