They’re squishy compared to balance druids. It’s just that you won’t get many opportunities to cast against them in a 1 vs 1 situation. Their defense comes from offense. Meanwhile, balance druids are just unkillable.
As the primary FC healer in RBGs, I get a lot of face to face interaction with Rogues. I don’t find them to be difficult to kill (or stop from killing), as much as their kit allows them ample opportunities to setup for quick kills where your defensive CDs play a major factor in how it will play out.
But you catch one in a HoJ and they die as fast or faster than any other class, IME.
The worst is when they work together. Two of them stayed at the GY in Eye of the storm yesterday on my mage and just camped me over and over again. Couldn’t get any help from the rest of my team so I just had sit and get killed over and over and over again.
We won the game, because these two never even tried to cap the tower. It was still a miserable experience though.
