I want to play any of the rogue classes but get stomped every time I try! I cant get decent but I dont think I have got past the maze with any of them! I have tried different way and things! I want to do it with Marauder the most since I like the way they work but dont know what to max or any ideas! I know what I max doesnt work!
Physical Wild and some kind of teleportation can get you out of most situations.
Otherwise, three clases play very differently.
For shadowblade get temporal magic at level 10 and abuse time shield.
Rogue is quite weak early game before you max stealth skills, dex and cun, so just play very safely. Don't fight many enemies at onece, lure them on by one behind the corner.
Marauder is actually more similar to Berserker, than other Rogues. I think he is most easy. Not much fancy tricks, but very durable. Max Fast Metabloism and Unflinching Resolve, then consider taking Bloodthirst tree.
For all of them, max dual daggers defence asap, it will save you from nearly all melee attacks.
