At T1 there is not much you can do with her than SL up to level 24 max, so i don't see a reason to get a uniform for her in that case.
Cap Marvel is crap and all her actual uniforms don't make her really good, so better wait until she hopefully gets a good one with her movie.
Wasp is not really needed since she is mostly used only for her T2 passive and her damage is not high, but its funny to kill T3 Caps and Thors (without ITGB) with her in TL now and then. I even killed some Apos with her :-)
I don't have Hulkbuster, i simply don't care about a suit as a character.
I have the x23 uni at mythic, It's a really big stat boost but I can't say that it's a great uniform, even at t2. I'd only get it if you love the character, it doesn't bump her up to a tier 1 character or anything, just makes her slightly viable.
X-23 - can't really say as I dont have it.
HB, Wasp - They're okay but there are a lot of other better options.
Cap Marvel - Stay away from her uni. It's not good and there will be a better one when her movie releases.
QS - this is the only good one. As I don't really like getting unis for my non-T2, it's a choice between HB and Wasp. Are there other unis you're interested in?
