I can't even solo Expert. Or Rag, even though Rag seems a lot easier.

Expert is such murder because of the goddamn buffs. Without Sol, you're just fucked if you can't Jack to Rage without a single Overdrive. And since I can't do that, I always have to just sit and wait for somebody to join before I start debuffing and attacking. And even then, half the time the idiots just go auto-battle (without even skill nukes first) and trigger the buffs anyway. So then it's a freaking 3 minute wait, plus all debuffs lost.
