I would like to suggest an increase for actively training a mount with bonus xp for the skill mini game and 100% trained skill achievement. I believe it's fair if one does active fishing they can increase their revenue, then likewise, active training horse and their skills should increase xp gains.

If that's impossible, then reworking the mini games so we don't lose our forward movement while we play it. Maybe have the auto path takeover while the mini game proceeds, and get thrown off if we fail. 

I always wondered why we didn't get any Training XP for ACTUALLY training our horses to use skills. I just trained my horse to drift, yet I didn't get any Training XP for that? If we got the same amount of XP per skill as we get from capturing/leveling, I'd sit through some of the lesser trained skills just for more variety in leveling Training.

Not sure how they could succesfully implement active vs. autopathing XP, I think that would be too much to deal with, but the skills should grant XP.

Exactly. For the active vs autopathing, I am only concerned with the skill xp transitioning into training xp. If they wanted to go through that coding nightmare to distinguish between someone pressing keys and afk that's up to them. As you eluded to training your horse to drift 100%, for example, should get you some training xp at least. Of course they'll prob think about it cutting into profits with the pearl shop, but there will always be players who can't be bothered to train and will indulge the swiping. Always.

They could even add it as a chase item with a treasure piece for a saddle or artifact that does it. Add it to Shultz loot table increasing population there and call it a day. 2 birds one stone. Idea factory here.

The only thing it would encourage is using bots/macros/etc as noone with a sane mind would suffer for this, just as they don't do it with fishing either.

I disagree.
