Hello friends.

I'm wondering what are popular options for Rank 5, 6, 7 after Quarrel Shooter 3?

I heard: 

Archer 2 -> Reighter 2 
Archer 3 -> Canon
Archer 2 -> Falconer 1 -> Musket
Archer 2 -> Falconer 2

Which one is most popular now in kTOS? And can they do late game (Earth Tower) well?

Also, I heard tomorrow kTOS patch change some Quarrel Shooter. Is it true?
Thank you. ^^
