Hi, I'm fairly new and played some 4- 5 times, and only with my buddy.
He has the core set and we agreed to collect the game together, so I bought Kazad-dum and started on the Dwarrowdelf cycle, while he's collecting the Mrikwood cycle to increase our cardpool.
Anyway, long story short, I actually had some time on my hands one night and sat on the sofa eyeing my expansion. I really wanted to play and thought: what the hell, I'll give it a go. And so I did. I made a deck with the expansion, and the 3 APs I own (WitW, FoS & SaF) and started the "into the Pit" quest. I really thought I didn't stand a change without the core set spirit cards and my very limited cardpool.
But what do you think? I made it! barely, Bifur died and Glorfindel & Elrond had 1 hp left, but I won. Who whould have thought?
I had a vey good & fun 1st time playing solo, and am itching to do so again and, I'm now getting the core set btw
