This topic reminds me of just about every video game and fantasy movie/show ever in existence. The art makes no sense with reality. A female with higher armor and defense wears next to no armor or clothing at all, but she can take down a dragon and only get her face dirty.
In many games, the higher the defense that the armor provides the more scantily dressed the girl is. A guy in similar armor looks like a walking tank, but the female looks like she's about to go to the beach.
Yeah, in reality, all the body types need rework. Gale should look way weaker than anyone. Wyll's not very strong either. My 8 Strength sorcerer should look like a scrawny toothpick compared to Lae'zel's Strength 17.
This would require a rework of a vast number of characters. At some point, you have to draw the line. This, to me, is not something that should be important in the game. 9 out of 10 D&D characters do not match their stats in any given session I've ever played. The players almost always choose visuals or miniatures that inspire them, not necessarily match their stats.
