I have been playing LOL for nearly 1 year, which is probably the rarest hero:

Top 1 Fan Mom Apocalypse (= = indicating that I have never seen this hero)

2 Gravedigger (MS has only seen it twice, or met it when she was in a group with friends = =. )

3 the pride of the leader (the big crab is actually very powerful. Crush the skin into a dog)

The source of the plague (the national service has been hard to find after several big cuts)

5 gay time keeper (MS has never seen = = crying. . )

6 tree essence

Others. . . More common. In fact, Akali Akali is also very common in the national costume, but it rarely appears after the official cut of 20% production.

PS. Remind LZ that the reasons for the unpopular heroes are mostly their own problems. For example, when Mama Fan is a * * *, she has three skills, but milk is not as good as Suo Laka's, and soul connection depends on R''. It's not good to go non-mainstream, but you have to work harder to practice cow X.
