I wouldn't really say it sucks, I like the update, it's very sleek and appealing to a newer "generation" and looks cute in a way. However your points are a little... Baseless? I understand it's your opinion but it seems biased towards the fact that you just don't like that the update is new and different.
1: That's very opinion based and I do like the appeal of this update, even if I'm not a fan of them moving so much around and to the bottom in most cases.
2: Why does that matter? You should be attracted to the comic not the person who made it, that's kind of the point of the thumbnails, to get people to come to your comic because it looks and/or sounds interesting.
3: The format is a little confusing at first but you get used to it over time, it's like learning something new, except you already have an understanding of the basis of it.
The staff is constantly trying to make their "product" more marketable to more people and this update looks more family friendly then the last since the first thing you see isn't, as others have stated, a lot of guy on guy hotness, while it's still there it's just pushed a bit farther down (Even if it's a bit farther down then most would like), idk am I alone in this?
