Vayne lore represents Vayne players, explained

I absolutely loved it, I think it represents Vayne players state of mind PERFECTLY -

In lane phase:

You are getting dicked on by your lane opponents so hard = Vayne is young, weak and monsters kill her parents.

The tilt and salt starts to build in from all of the dicking = Vayn's hatred for black magics.

Nevertheless, you didn't choose to play Vayne for nothing, so you keep going for that cs and tryharding in general with the help of your much needed (!) support = Frey notices Vayne's determination and help her to get stronger.

Mid-late:

Now you are salty af and tilted out of your mind it has been around 25 min of ass pounding for you and you just had it.. so you throw some toxicity towards your support for a little mistake he did = Vayne is consumed by her burning hatred, the moment she realize Fred used black magic she kills her (flam her).

Late game:

Finally, at last, you are strong now and can sodimize all your evil opponents but because you got salty af it's personal now and you will enjoy it! It's time for them to PAY hahahaha = Vayne enjoys it, nothing even comes close to killing enemies in a slow and agonizing fashion.

After the game ended:

This isn't in the lore now but hopefully it will be some day.

You obviously won the game, after all you are Vayne in late game, but you can't stop thinking - was it worth it? All the salt and flaming the person who helped you through the long lanning phase, you don't know what is right anymore, why continue to play? = Vayne's past is starting to catch her up, all the things she have done, the monstrosities, heavying heavily on her soul.
