 Hi friend!

Yeah, sorry, I missed this thread, but I shared the following post yesterday in Battle Familiar and Pact of the Chain (EDIT: StonyMac was there, indeed)

 Hola amigo! Thank you it's okay the thread may have been in relation with another game feature that forgo attack, like Beast Master but all i remember was the funny justification. 

Yeah, that was a witty comment posted by jl8e in one of the linked threads.

I agree that War Magic would work with Haste. I just don't see, within the rules, what the difference is between an extra attack granted by Haste and an extra attack granted by Light/Nick. They're both done as part of an Attack action

 One is conditional on using a Light (possibly one with Nick) weapon to make it. The argument is that, because of the preconditions, you can't go "I'll attack with my scimitar... just kidding, I cast a spell." It has merit, but, as I said above, there's not enough text there to officially rule either way.

So I guess that instead of "kidding, I cast a spell", in this case it would be "kidding, my familiar attacks".
