yep. the rogue is the worst. He's not meat shield as fighter, nor strong melee damage dealer as babarian. His skills don't even have any kinds of damaging skills.
The ice stage is the hardest stage. The lava stage can be easily win by getting flight ability items and you can easily make enemies kill themselves by snipe on fireballs fire elementals spiting or just make enemies on the way on trail of fire orb. But ice stage's enemies who have ice shooting ability also have ice bomb which blocks from transpassing. Combining those two are really hard. Also the cold gauge forces find campfire which also can be frustrating when there's statue nearby
