I'd do a Rog/Bard:
You 've got a big range, high damage, and you 're str.
Bard gives you the required speed to lvl up quickly and it prevents you from aggressive mobs.
Also if you'll get bored from soloing you can go and lvl up in a 8er PT as a Bard
Also with all these Sun weapons and SUN Armory you'll be a really good damage dealer and even though choosing bard as a subclass you 'll be able to tank some good damage
Best regards
