I just tested "Roar," and at max rank without any mods the damage buff lasts approximately 15 seconds.

So basically, having a max Continuity on your Rhino will give you 5 extra seconds of the damage buff and 3 extra seconds of the stun... AKA not worth it. Better off with a max Streamline.

30% less cost on all abilities > 5 extra seconds of damage buff
