Its been a long time since I last played ROSE, at the time I was playing a muse/cleric with the sword summons and the pink dinosaur thing. It was a lot of fun while leveling up, but at a certain point it hit a brick wall since high level mobs would kill the summons in 1-2 hits, which wasn't fun. At the time there wasn't any plans or notions of plans to buff them, so went back to playing other stuff.
Are summons more viable now? Is it viable as a class (i.e. they don't die when sneezed on)
Same goes for the mechanic class with his black knight and archer/soldier things.
