While entirely unrelated, C9 (Continent of the Ninth Seal) has a class that uses Chakrams and is an absolute blast to play. The game itself is pretty awful though, but the classes are fun. Think of it like awful KR instanced dungeon grinder game meets dynasty warriors (which also has a Chakram character btw).
The game is repetitive and grindy, but the combat is compelling enough to hold you until you hit max level IMO.
