Would you need an english version?

Not really no.

to be honest, where we are at now with the english patch is plenty enough for me.
Like, there really isn't much left to translate that i need to know to get max efficiency out of the game.

I would still have to say yes. Would avoid people having to use limited programs like WTFast to be able to get the most out of their internet connection, in PvP.

Wouldn't mind having the game full english but the english patch is getting more translations everyday and I don't think it will be long before pretty much everything is translated. Might even make the game more popular

We're getting close. I for one, like to read the quests and follow the story. With an actual English version, the game would be more popular and have more English players for sure.

Use the link in my sig if you want to track the progress.

I don't know why there's no English version.
Does anyone know?

Nope. Just hasn't happened. No matter what ANYONE says... No one really has any idea why the producers do anything or don't do anything. We can only guess.
