WotLK Warlock talent issue(bug?)

[duoduozi]

I was upgrading and digging into my damage recount, then I find something wrong with "Fire and Brimstone". It says that "the critical strike chance of your Conflagrate spell is increased by 25%", but actually it only take effect on Additional Damage(DOT), the instant damage of it is not increased. I don't know if it's a bug, so I hope u can check it.
Looking forward to your reply.
