This was an okay scanslation, nothing to get up in arms about. If you keep at it you'll become solid in no time. There are decent suggestions in the comments, you just have to ignore the idiots that don't seem to realize they are owed nothing.
Regarding the manga, fun chapter, this adaption really seems to capture the fun over the top nature of the source material. I agree with previous commenters that Nonna's assets are not as over the top as I expected. She is supposed to be overwhelmingly busty, and with this character design I feel like she won't distance herself enough from other busty characters that will be showing up. I predict they will simply be drawn bigger as needed lol.
