Hector, the Distant Counter fodder

...A lot of units.

Do you have any possible units that you were contemplating giving DC to?

Basically, the units you aim to use for high tier arena.

If (high tier) arena is of no interest to you, then almost any unit that isn't ranged.

I'd say Sigurd and Myrrh are among the two best users of DC, second only to Effie and Winter Robin if you don't have a usable Hardin.
