blind, debuff, frozen, stunned, knocked down...
Rogues are vulnerable to all of these as well.
Warriors do move slower, but they have Bullrush, Phoenix dive, and with a single point in Marksman they can get Tactical Retreat as well. Not hard to catch up to any enemy, especially when they have a 15m range knockdown, in addition to bullrush (which also has 15m range + aoe knockdown).
Killing a single enemy, even a boss, isn't that hard. Handling all the extras is what's challenging. Once a rogue comes out of stealth, they have very low survivability. They need to spend AP cc'ing enemies or else they're going to die.
On hard difficulty, you definitely do need to use crowd control. Not to mention that Bully turns knockdown into a huge damage boost.
