Rereading is a trip. You spot all these little things and it's just wow rude. There's so many little things that stand out. My most recent one is Armin's words here.

There is some plot and action. The big stuff is kind of on hold at the moment because of the world being on fire. But before that there was an expedition to build a new base and there's the revive a dragon plot going on. For smaller stuff there's quests/jobs where characters can go outside the city, explore and fight monsters.

Sample should be easy enough. There should be a Tdm and mods are pretty open about what can be used. Though I can't say anything about apps, Mikasa's was the first I'd written in just over a year.
