Twink level

Im planning to make a twink rouge, what level must I go and why? I want an active twink level. Thank you!

8-9 or 15-17 I'd say are very good levels for rogue and pretty active too

Is level 10 active?

Yup 10 is quite active as quite a few 9s have levelled up and guilds have started to recruit 10s now too
