ANYONE ABOVE A- IS TOTALLY PLAYABLE IN MOST SITUATIONS. B-C are playable in a lot less. and D is Torvald.
It's Io. :)
Hard to find a place these characters will not do well. Buck is hard to kill even in late game, Inara pairs well with any composition, and Viktor will always do his job while being hard to dive (god bless Predator V)
Harder to counter than A+, but still can be. Regardless, they will perform barring poor skill from the pilot.
Will do their job well, but can be countered effectively with the right draft/strategy
Supplements for A+/S- picks. Can still fit in nicely if you're comfortable on them.
Underexplored/just countered by the high tiers. All can impact a game heavily in good drafts/even have places against current meta.
Decent potential, but outshined by other choices. Can still do well in the right hands.
When the stars align
They will never align
