So... serious question here. Genuinely interested.

When Acnologia calls Irene Zeref's apprentice, MS translates his statement as, "Considering your Magic is learned from the Black Mage, it's fairly impressive."

Now, while it is somewhat ambiguous, this statement would normally mean that Zeref is either a pretty bad mentor or plain weak. However, I thought it was just a tl oversight. For something on the lines of, "As expected of from one taught by the Black Mage, your Magic is fairly impressive."

Then we have CR, where Acnologia seemingly blatantly derides Zeref's prowess. "Your Magic power is impressive, for someone trained by the Black Mage."

So... does Acnologia consider Zeref pathetic, or are the tls by CR and MS lacking? Both cases seem equally possible, tbh... Plus, if he is demeaning Zeref, this makes for a nice quote. :P
