Couldn't think of a better title, but another game did this awhile back as a way for fighters to pay respect to one another. Basically, you list all the classes and then think of people that have given you the best fights, think they're one of the best to touch it, or a name you just associate the most with a class. Also, it was good for people to use as a resource for who they should go to in order to ask questions about the class if that person still played. Probably best to use spoiler tags to avoid spam.
Ascendril: Tahl, Xavin.
Bloodborn: I didn't know many that fought with it, but Exzuryx legitimately made the most of the class in my opinion.
Infernal: Didn't know a soul that used it.
Paladin: Hadoryu, Edhain, Yos.
Sentinel: Missari (as far as best fight I've ever had against another Sentinel)
Shaman: Illidan (if you used Druid, it'd probably still be Illidan)
Teradrim: Feichin, Haedyn
