Criterion savage, only for i625-i630?

In that picture, Yoshi-P is only item level 618. It says he can't enter because it's for 4 people. It does not say he can't enter because of item level.

If you can't enter content because of item level, it actually says and specifies the item level you require, which we would be able to see in English. Try unequipping everything and looking at raids and dungeons and you will see.

You can also enter DSR with i580

It's 618 or below, at least according to the picture.

Ultimates seem to be special and don't have an "Average Item Level" that you must meet. Of course, this item level is not relevant if you queue with a full party anyway, because a full party can ignore the item level requirement since a patch that happened a long time ago now, but if there is an "Average Item Level" that you are not meeting it still says.

Because a full party can ignore the item level requirement, it's less of an issue, but then we can say the content is tuned to that item level and being below it might be too hard. It seems like it is 618 or below so you can probably use crafted gear.
