Most challenging class?

[Siberys]

Mmmk, so I went through Hellgate london a few times, thus far I've noticed Blademaster and Marksman are the easiest classes to handle when going through the game.

What's the most challenging class, what class just makes the game so much harder that you need to be an experienced player before even considering? Summoner maybe? Or Cabalist?

And with what build? I want to make the game as damn near impossible as I can make it, as I like a good challenge.

A Cabalist can be pretty tricky to use. If you get the skill distribution and selection wrong, then your character will end up as fodder for the stronger enemies and the big mobs.

Probably the hardest to use is the Summoner. When up against bosses, his summons die pretty quickly and I have yet to encounter a decent enough gun made for the Cabalist/Summoner class. That being said, the Summoner is extremely effective against the normal enemies that you meet. Kind of like the Necromancer in D2.
