My reasoning: Benjamin: makes banks more efficient, and bloon trojan is so useful on round 40 since u dont need to deal with those cerams. Sauda, even though her only great weakness is the range, shes still super good, her level 10 ability saves games and overall, one of the best heros but she doesn't have that spark that ben does. Obyn is in A because magic strat with druid: OP but it's kinda getting knocked out, but he can really be helpful in CHIMPs. Same with quincy, he can be useful for CHIMPs or Impoppable. I chose Etienne for A because global camo detection obviously. If you can get him to level 8, you dont need to spam 020 villages now. He almost got downgraded to B because his popping power is below average but I'll keep him in A. Next is geraldo. Welp, we know this one. Pat fusty is in B because his level 3 ability is good, but short range OOF. Adora, dont use her much but she's useful sometimes. Striker is in B because moab mauler strat is op especially double hp MOABs but he's more support not popping power because he needs to buff other towers in order for him to work.. Admirel brickell is in C because, well.... She's great but u cant even place her in some maps. Next is Psi, I just dont think he has a lot of spark tbh. Churchill is next, he's good but hes EXPENSIVE. Gwen is up next, and uh yeah.... I dont like her that much. Next up: Ezili yeah.......... shes pretty bad but shes good in freeplay.
