What is wrong with having strong female fighter types? So for once the guys are mostly the casters. I'm totally ok with that. I can't envision the game without Lae'zel or Karlach anymore and they are just perfect the way they are. You have a strong Dex fighter with Astarion, who can own a battlefield easily. You will have Minsc later on, who canonically is very strong. Wyll as a Bladelock is a good melee fighter, I don't see the problem here. You can even redpec him and make him a warlock/paladin, if you do like. The only character not made for frontlines here is Gale and maybe Shadowheart ( though she is pretty tough, but I like her more as a caster). I think, that Halsin will be pretty tanky too.
Nothing, and no one said anything of the kind. No need to strawman to have a discussion. I don't think anyone has a prolem with strong female fighter types. It's the proportion between STR based females and STR based males which is a bit off. I don't see how that's a very difficult thing to acknowledge. Gale and Wyll are simpy and a bit pathetic. Astarion is... let's just say some find him unpalatable. All females are strong, confident and competent. No single character is an issue by themselves, but in sum it seems off.
I hope Halsin can make up for the deficiency in the male department, too bad I have to go the whole first act without a competent male figure in my party.
