Trainers has no benefit(t9-t10) for their hard work, why they dont add additional +xx % Failstack depends on Training Mastery or something like that ?

I got feeling that my invested time in Training mastery are worthless, the benefits from it are not enough.

Also why not implement Exchange t8 horses for Fern Roots? this can cure the horse market that are broken due to FREE  T9,

or fern roots for imperial seals.

#Pearl Abyss, You can make system that will, allow to exchange certain numers of t8 (dialy)(weekly) for Fern Roots that deppends of Training Mastery -This will Definitely Cure T8 Horse market and Reward Trainers for Their Hard Work.
