Channeler is sort of a generic term meaning someone who channels magic (which is what imbuing allows). A farmer can be a channeler, but a channeler doesn't have to be a farmer. Does the unit somehow behave unexpectedly?

It behave himself correctly in both means - like Channeler and Farmer alike. But it seems logical to list both strengths for himself, in the character page and in the quick info. Alternatively, it could be the equal correct to have only "Farmer" in both tabs. But replacing one with other in one case and remain first one without second in other case looks inconsistent for me!
