It is a good argument but it invalidates itself most of the time.

Aspas has an average Raze but has an exceptional Jett.
Something, despite playing in Tier 2, also has an average Raze and an absurd Jett and both are good duelists.
Mwzera has a great Raze and was a duelist his first year, but soon switched roles so ¯¯(ツ)_/¯

The argument might make more sense using Neon than Raze, but I still don't like it much.
