Eh, apologizing is pretty common in Japanese culture anyway from all I have been told who are experts on the subject. Or at least self proclaimed experts. I'd rather him think about the art direction and the possible meaning it has for others rather that be "sorry".
Also, this isn't an "Oh my God I'm so sorry I feel terrible" response. So I'm not to worried about his feelings.
Dungeons & Dragons and the work of J.R.R. Tolkien
Eh, a lot more Dungeons & Dragons than J.R.R. Tolkien. Also The Elder Scrolls: Arena did this sort of junk in their games. And it was pretty obnoxious there, too.
People keep defending art choices like this as "hey it isn't sexist because the guys are so muscular". Not the same, those dudes aren't there to look sexy to women at all. They're chiseled to look "manly" and capable. Having a figure like that would make you a hard as iron warrior. And the design is like that for players who want to feel like a hard as iron warrior. That Sorceress class, on the other hand, would have trouble even walking with breasts that large.
Also, for those saying people only complain about females with proportions like that, this is a problem, too. The fact that so many dudes in video games are these hard-boiled macho stereotypes with gigantic muscles is possibly as stupid as the fact that so many female video game characters are Ms. Fanservice with too large of breasts to even carry. Just for radically different reasons.
Radically different reasons for why people say "but but men are stereotypically formed for sex appeal too!" think. The problem with the male characters is how they force an unhealthy image of masculinity which is obsessed with hyper-empowered, dominance. The idea of this gigantic man with gigantic muscles and a huge beard falls right into the idea of many men thinking manliness is an achievement and the top of the human totem poll. And very much reinforces sexism just like these ridiculously buxom women. Just not in the way many defensive men would like to admit to.
