Yup need a respec. I'm not playing cavalry with a horse like this. And tbh...I doubt anyone will pay for a champ courser on market.
A courser is now useless. It's acceleration was already down, and with all the village/hilly maps it has no hope of getting to full speed.
Edit:
The only way this makes sense is if you add 10x more open plains type maps to rotation so cav actually has a chance to reach close to full speed.
Right now there is no reason to use courser ect. May as well just use a rouncey.
