Very new to this site/game all of this actually will have approx 45000 fg available to me soon -- where should i start? Looking for a fast way to do the quest

Read everything I have seen thus far looking for some help on items I think rogues look cool but whats the fastest toon to run up with ???

If you plan on spending money on ls now is a good time to start, maybe
rogue with dagger, ee scales and dex charms will be nice

Realistically, there is no such a thing as ''fastest'' anything in this game.

It all depends on the gear that your char has, and how they inter-act to make the char work properly.

Play the game and learn.
