Honestly, that just shows how classes were popular. I can’t say anything against ktos rankings (I would like to see Klaipeda/Orsha ranks too xD). I totally agree that Clerics and Wizards were betters than archers.
But as an Archer myself, some cases Archers were good: Had good weapons, stat distribution and or knew how to PvP his class. Example (excluding me): Kazuto’s Ranger SR, Shiken’s QS SR, Mio’s QS SR, Korasai’s ScoutWugushi (sorry, I can’t remember others atm).
But there was a really bad problem at that moment: Full DEX builds without high damage skills and good weapons. Also others such as Ranger 3 that Spiral Arrows hit me on my archer for less than 1k, Scouts that gives out on cloaking state to hit Ausrine (we see them even nowadays), people hitting Revenge without swapping weapons before even knowing they had revenge.
It was way easier to reach higher ranks as Clerics and Wizards than Archers and Swordies, again, I can’t say for swordies since I don’t play them.
But playing Archer myself Rank 7 was way better.
As long you didn’t have a messed up build/stat distribution that just won’t work for PvP with your class at that moment and that’s another topic of balance.
Also, not so good reason but as well Rank 8 brings less powerful archers while it brings better ranks for clerics, wizards and swordies.
