Did he just say "Every time text changes, posing changes too" Like WTF no wonder they take forever -.- I'm starting to think they aren't very bright, like yeah I get it, you want the pose to suite what they are saying, but that is why you trim and fix the text before you pose, Like seriously do they pose, fix text, repose, refix text, repose OMG.
All in all I can understand wanting to change something last minute cause you realize you aren't satisfied with a specific sentence, ok ok, but it's not supposed to be a massive thing unless you have no idea how to optimize your workflow, which seems to be the case
