Meteor strike training "abuse"?

Crumena is a dragon/field boss. Crumena can be accessed in G8 final. G8 final can be repeated if it is not finished. Using these facts and basic logic, you can easily figure out that Crumena is the easiest way to access a dragon if you have access to G8 final. I don't remember anything mentioning that using Crumena as a target was "abuse". In fact, if it was considered abuse, why would devCat even allow it as a target for meteor training in the first place? You'd think they built a list of monsters that count rather than a list of monsters that don't count.
