The T10 unicorn is a terrible design, as it stands the T9 is better. T10 looks the same as the T10 doom and sounds terrible, the water running skill is useless (can't go anywhere even after the buff). The amount of effort needed to get a T10 is absolutely not worth this horse, I regret ever ascending it. I will be using a T9 until the day PA actually makes a useful T10 unicorn. For anyone who has not used the horse, here is an example, I cannot run from Iliya to Velia without stopping to recover at minimum 4 times.

PA is currently discussing buffing T10 Dine by removing the water running limitation. You can see it on the Adventurer Feedback Board. Besides that, i agree that it doesn't look good and could use an alternate appearance skin.
