What does "Lore" spells mean?

Typically, they are spells that are dropped by the hoard packs that have "Lore" in the name. However, within the last few years, there's always been a change in which people can acquire these spells which change the overall definition of Lore Spells.

Speaking of which, ever since the introduction to Loremaster, lots of people farmed her not only for gold and tc but for the very rare chance to get a new spell. At the time of the patch release, it really was something new for the wizard Community and it was very rare heard of (Unless you were farming the mooshu bosses for spells). Have you ever noticed that the loremaster drops from herself and not from any other lore pack? Well, I based this that you get it from the boss itself which is why spells like these are meant to be op. 

                          

 You can actually argue the same thing for fire's spell, Burning Rampage which is dropped by the Stone key boss in avalon called Lambent Fire. As it stated at the start of battle, "I am a wretched spirit, once long ago a noble knight. I quested to find the Horn of Glory. But I fell, and remained trapped here to flicker like the dying of the day!" This indicates his backstory that he was a knight who encountered this monstrous beast of a firezilla but it fell down to the knight and crushed him into a ghost. So now he is trapped for eternity in the caves, hoping for eternal revenge. As for the minions surrounding him.. I guess its just KI filler. 

                                                                                                                                                                In the sense, you can say that lore spells aren't really meant for packs anymore, they are meant for the keeper of spells, Loremaster. But here's the thing, if it drops newer and newer spells such as Athena Battle Sight then why doesn't she have that added as part of her attack arsenal? I know its asking for more difficulty but in reality, she was meant to be designed that way. Anyways, i've gone on this for too long and I will conclude with this: Lore spells in my definition are that are dropped off bosses based off upon what the design of the spell visually and from a story standpoint (if you get what I mean).

So what are your definitions of lore spells? Post it over on @BurningSpirals
