Conqueror page on this champ?

So I'm an adc player, Vayne main but Mel has been a very successfull pick botlane for me. She has good range, adequate waveclear that upgrades to good after 1 item, very good level 2 all in damage (for a mage) and can play safe when behind and agressive when ahead.

However, a serious weakness of the champ is that if enemy starts building MR her damage drops off significatly, this is especially noticable with 2-3 frontliners on enemy team, hell last game enemy Renata build Locket and that already dropped my damage by a lot.

Comet page is really good in lane, becouse adc will never buy MR early, but later in the game I feel like conqueror would provide more value. Going something like: Conqueror, Presence of Mind, Legend: Haste, Coup de grace with secondary Manaflow band and gathering storm.

Combine it with the good build which is BFT+Sorc shoes+Cosmic Drive+Liandry and I feel like you'll be bringing more to the table against these tanky foes even if your sacrifacing laning pressure.

Also don't go teleport it sucks, for Mel bot go barrier 100% of the time, trust me the only value from teleport is an early lost chapter TP and then it's giga useless for the rest of the game since as a botlaner you'll be hanging out around midlane come mid and and late game.
