I left this at 0 because I wasn't sure how much Shadowburn actually cost at 56. I don't have beta and on pservers I think they got the price wrong as it does cost 2g20s but it is the only talent in the game to cost anywhere near that much. So I need someone with beta to verify.

Hey thanks for that. Are you Honored or above with the trainer's faction (I'm assuming he is with Gnomeregan Exiles) or are you rank 3 (Sergeant) or above or both? These both give 10% discount up to 20% total.

Correct, he is with Gnomeregan Exiles. No PvP rank and only Friendly with them. I am Honored with Ironforge if that may have an impact.

Thanks! <3
