When using Fellhound as my campaign farmer on auto-run, the game WILL NOT follow team skill-use settings on the campaign boss (stage 3) of the run. 

Despite completely disabling both the A2 and A3 skills for every boss level campaign stage, Fellhound still uses all of his other skills on stage three of the boss level. WHY??

I have not tried this with a different champion yet to see if this issue exists across all champions or just Fellhound. Either way, it's frickin' annoying because it often causes the champion to get killed and the run to fail. Otherwise, he can and does clear the boss level every time if the game would just follow the disabled A2 and A3 skill settings I have set.

So please, either tell me a good reason for the game not operating as expected or realize that you have a game bug that screws up gameplay for whatever reason, at least for this particular user.
