Not using those exact words, no. The term "lack of" generally means missing or a lack of something, which in the case of AoE and MA is false. MA has an AoE with Dragons Tail, so saying it is "lacking AoE" is a bit of a misnomer. It stands to reason that someone saying the set lacks AoE when it has an AoE in it, it would mean the person is looking for more AoE. Not difficult to understand.
