I have a few and a bit of a story for each one.
Partially due to a lack of yellow hitters that is still ongoing, not that there are many of those, Chao still features heavily on my A team yellow stack, though he’s situationally supplanted by my +17 Gretel depending on circumstances. I as a player I prefer sturdy snipers as an offensive strategy, and Chao fits the bill. Full attack path. Not the heaviest hitter by a mile, but for my yellow team he is.
Same as Chao, I just prefer snipers as an offense team in general. She doesn’t get much credit, especially compared to her big sister Scarlett, but Kelile’s stat balance works out for me most times. She has a ridiculously high DOT that often helps keep down rogues and fighters. She’s not the best sniper by far, but much like yellow, red has a bit of a dearth of good hitters, so I work with what I have. Full attack path.
Was my first druid I levelled, partially due to not having Melendor at the time and partially because he was my first 4* green, he’s mostly benched these days in favor of Kingston and +18 Peters, but he still comes out against buff heavy defense teams and in wars. Like the other two above, he’s distinctly average, but he fits for me and my playstyle, and there aren’t many better options in classic green. Some days I think of pulling off emblems, but I haven’t yet.
Only really use for yellow Titans and late war flags. Idk. I don’t really have any other sorcerers to give the emblems to. He’s alright.
