Just to comment on some of the responses that followed mine. It’s been my experience that when I ran the RR shield, even with stacking DR up to nearly 50%, I’d go down far faster than I do with an actual shield. This tended to happen when I’d get hit with certain elements, like incendiary, and it was especially true if the M3 modifier included a negative to elemental resistance. Zane’s health regen works awesome against a single enemy, but when you’ve got multiple enemies hitting you, in M3 TVHM, the health regen isn’t enough.
As for the skills you lose without a shield, there are two: Adrenaline and Confident Competence. The former is Action Skill cooldown, and the latter is gun damage and accuracy. While I can usually keep up Barrier and SNTNL a fairly long time with CCC, there are inevitably times when I can’t and they go down. Having my Action Skills on a lower cooldown has been essential to my survival, especially when I’m doing something like Slaughter Shaft. With gun damage and accuracy, you could argue that the bonus accuracy isn’t a huge loss, but losing the bonus 20% gun damage is a big deal.
So my opinion, based on my own personal experience, is that if you’re playing smart, you don’t need Rough Rider to bypass the CCC mechanic. You’ll usually have no problems keeping full shields and health behind your barrier in order to proc CCC for the Barrier/SNTNL refresh. (The mistake I often see Operatives making is that they leave the Barrier static and don’t bother picking it up, which is fine until an enemy closes and gets inside the Barrier.)
I will concede that Brain Freeze with non-cryo weapons is effective, and I should look for more Anointed weapons with the cryo damage element. It might make all the difference with Anointed mobs as you’ve said, which are my single biggest frustration in the game on Zane.
I believe he was referring to the Confident Competence skill that I mentioned above.
