I have been into ToC normal many times and to be honest the mounted stuff is fine if it doesnt bug out.

1. If you back your team all the way up against a wall they get line of sight issues.
2. Pre-transition from mount on Champs can bug out (trampled all 3 for about 5 minutes before I gave up and zoned).
3. Watch your targeting post-transition on Champs. For some reason I could not change target on my main screen.
