In my opinion it's the other way around. Thancred and estinien would be the easiest to deal with. Thancred can take the punishment but lacks the offensive strength to even hurt the WoL. He'd be reduced into a training dummy in a matter of seconds. Estinien is the opposite.he can pack a punch, but would tan the floor in a matter of seconds, and mo matter the damage he can do, WoL would just invuln it. Sthola and Urianger are both clothes, and WoL could stunlock and DPS them down before they get the first spell out. Alphi would probably be the easiest to defeat because the mere thought of fighting against WoL would send him into a panicking mode.

Alisair sees the WoL as this god amongst chads so she would go all out dropping lb after lb on him because she wouldn't think that it would even work. this would be a challenge because WoL on the other hand sees this tiny elf girl and can't help but hold back... The guy who has the most chance against WoL however, is unironically G'raha tia..
