Rogue Ultimates still a bit disappointing

I still find the Medicinal Herb and Aimed shot Ultimates underwhelming.

I'm not sure how other rogues feel but a few ideas I have is:

Medicinal Herb -
Add damage reduction percentage or immunity to stun/bleed etc. to Herb ultimate to spice it up.

Aimed Shot -
Increase damage even more OR allow it to stack/fill twice during map run as an option so there are two shots possible if you save them up. In other words, when it fills up it gives you one Aimed shot credit, but then it starts to fill again and if you don't use the first fill up it gives you a second as well. This would obviously be to use at a boss at end of map.

Just thinking out loud. Seems like warriors and mages are pleased with their new buffs to Ultimates.

I agree, rogues aim ult is crap. It definitely needs another buff.
