Just tossing some ideas that would be cool.
Main hand torch:
This is really intresting and I think a cool concept. Think like lara croft adventurer style torch. It could have some really cool aspects. Especially mixing with offhand pistol.
Rifle:
Not much to say but that shadow sniper assasin is epic. Physical damage based.
Longbow:
Maybe a faster version of rifle, lower damage but faster at and more condi based.
Off Hand Sword: besides that feeling like Kirito from SOA would be cool :P. I think it would cool to it have a more party riposte style gameplay. (S/S #3 should be sword drive)
Staff: maybe like a quarter staff or something. Not like a shadow Mage or anything but a physical 2 handed melee weapon sounds epic for thieves and is totally necessary. Have it more low damage but CC based like hammer for warrior (except not stupid OP broken).
Main hand axe:
It could have a really cool fast paced gameplay with a “grapple hook” style where it could attach you to people and they couldn’t leave the leash until it expired
Melee based with slow high damageing attacks perhaps?
I don’t know on any of the stealth attacks for these weapons but I do think that these are probably a good list of candidates for new weapons for thieves.
Feel free to come up with what the skills would be for these though
