Originally intent was for Toutestsu to be S+ in arena, but his usage has massively dropped with the better arena leaders like Michele, Krantz, and Hadaron. Not to mention he requires a very specific team for dealing high damage with no sustain. Griff is an example of a unit in arena that has a massive nuking capability. His normal hit combo does twice the damage what Ark's massive hit combo does. Also Ark is pretty damn good for producing BC and is overal op in general. Synergy is how much a unit would impact a team and how often they are used combined. Ruby is a very good spark unit, but other than FH, I don't often see her. Ark is an overall better unit at producing BC because of how versatile he is.
