SoulCalibur’s base mechanics, particularly of this game, renders the usual utility of tier lists… I won’t say ‘moot’, but I must urge you to creatively approach characters that appear weak or strong.
It was SC4 and talk of how “weak” Taki was that motivated me to work her into a monster online. The experience was the genesis of my contention with the slavish devotion to tier lists in the FGC.
The game can’t play for you. Characters can’t play for you.
