Who told you that i have quit the game @hoomanchoo? Am assuming your talking about me since im the top arawn ranger. I play on epona now so feel free to hit me up there whenever.
As for the top rangers in the game, there are a lot of strong rangers who know a lot about their class and are active on the forums. Legendz, reef and myself are probably the 3 most active on forums. Reef has sorta disapeared recently but im sure will be back around soon. Some not so active on forums are limbow, sharpshooter7 and xwolfex. Those 3 are all on epona if you ever wanna talk to them. Even chaotic, before playing nuada they were a very knowledgable ranger who played on gwydieon.
As for the strongest rangers in the game, bluestar is without a doubt the best geared ranger however that doesnt always mean strongest. I am not too sure about if blue gear swaps or what build or anything so cant really comment there but certainly blue legendz and me would have to be 3 of the strongest rangers that i can think of in the game currently.
