I was thinking about this new talent and am wondering how this spell is going to work with demonology spec. I mean with the possibility of having a permanent infernal/doomguard why would we ever use our wrathguard/infernal. A big part of being a demonology warlock is the perk of the exclusive stronger pet and with this talent it seems like we lose that. I don't know though, I may be wrong with this thinking and maybe someone could help me out in explaining it to me.
I also was wondering what will happen to our temporary pet spells infernal/doomguard or abyssal/terrorguard. they are somewhat of a dps increase are they not? so choosing this talent do we lose them?
