Yeah, while I'd choose different examples I'd agree that I'm skeptical of always sticking within the narrow bounds of standard archetypes. Blacks and good plats are so powerful in part because they often have the stats necessary to stumble ass backwards into filling a secondary role on top of their class's usual specialty. For example, AW Elizabeth's primary shtick is dps but you might be surprised by how often she can end up working as a her own lightning rod thanks to her 2.6k health and 306 armor. Once paired with a healer you'll find that most ranged units will melt before her attack rate before they're able to polish her off. Yes, in a perfect world you'd probably want to trade some of her stamina in for even moar firepower but in the meantime that extra durability is hardly useless.
