Dorcas

I recommend foddering it for Quick Riposte 3, or for Infantry Pulse 3, or for Fierce Stance 3. All three of those abilities are like, A+ Tier abilities, just behind things like Steady Breath, Distant Counter, and Wrath.

Because honestly, +Spd is a useless boon. The bane doesn't really matter, since Dorcas can work with an Hp, Res, or Speed bane imo (although speed is preferable by far), but the +Spd is just really questionable.

If you really want to use him sure, he's a great unit either way and this isn't as detrimental as say -atk or -def (though his innate Fierce stance helps the former).
I personally would fodder for QR or Fierce stance though.

well it's not a crippling IV like +spd -atk/def so it's workable.
But infantry pulse is kinda not good on him(Maybe)

Yea. If you can give him fortress res. Otherwise he's hot garbage.

i have the same IVs, and he works fine still imo

Give hm suppot to boost spd as much as u can then he can avoid doubles snd be a fantastic tank!
