As someone who still plays GW2 with over half my 30+ characters as Charr, Charr are nearly heavily abused by the GW2 design team just slapping overstretched armors on them as opposed to tailoring them properly.
They have an obvious preference for Human/Norn/Sylvari(and to lesser extent Asura) and leave Charr armor and the resulting horrendous body/size clipping issues as an afterthought.
I feel for Hrothgar(and Viera) players here. I really do. The dev team needs to take some time aside to fix Viera and Hrothgar, content be damned if you can't play fashion properly.
