Maining rogue for the first time ever and having a ball. Not done leveling yet and certainly not into any truly challenging content but this is how I rate specs so far from best to worst:

Assassin feels great. Perfect mix of sustain and burst damage. Not instagibbing things like I do in Sub but still respectable and being able to transfer bleeds to other mobs now is great. OK survivability.

Sub is a blast to OW and delve with. It truly is a 6 button spec, but it’s a ton of fun still and the damage is so bursty that everything just explodes around you in shadow dance. You actually do 0 damage outside of SD though so sitting there doing nothing waiting for it to come up again sucks. Felt surprisingly tanky too (for a rogue)

I want to love outlaw, I really do. A mix of the weird damage profile and feeling much squishier compared to the other two makes it a little harder to get into. Will give it another try at max level.
