When your gamplay sucks, and your encounters suck. I am not playing your game.
I'm starting to want to see Mishu-mishu play his own game on Core. Just to see his reaction to his own game.
Once I reached level 5, and finally had a party of 6, I didn't encounter serious difficulties on Core.
My problems were when I was still lvl 3-4 and my party consisted of 5 chars (of which my MC wizard was pretty much useless), because I shooed away Nanio and didn't get the tiefling. I thought he was gay but it turned out he just likes jewellery.
Wait till fucking gargolies attack you in tight area. It's really uneven as heck.
How tight are we talking about?
But seriously, I just got through the mountain pass in Reliable Redoubt. My party is lvl 6: MC Wizard, Paladindu, Spidergirl, Lestat wannabe (Daeran), Ember, Camellia. I cast a couple of buffs (Bless, I had the food buff from resting, and then spammed the Protective Luck ability with Camellia, didn't even need more buffs like Haste for example. I also cast Burning Arc a couple of times, it worked very well on the Gargoyles.
