Tossing this in spoiler tags; nothing story-related or anything, but people might want to explore themselves and such.
Here's my team standing over the dead Spidest at the bottom of the mine near the Machine Graveyard.
This is the fourth party I made; the first three were quickly abandoned as I learned the system and realized that I had either wasted exp on random skills I didn't need or didn't like the party's dynamic. I've got, in order:
Fareem Guardian/Warrior with axe/shield
Human Warrior/Brawler with greatsword
Human Warrior/Scholar with spear and lightning magic
Scuri Scholar/Sage with ice/life magic
I quickly found that the best way for my Guardian to tank damage was to
not use Guard; it seems that the AI doesn't really focus targets, but it does like doing damage. This means that a target using Guard will be ignored unless there aren't any other options; once I figured that out damage control became a lot easier.
I do wish that there was some way to restrict enemy movement similar to the Rampant Aura from Tactics Ogre' it would allow my formations to be much looser than they are right now.
Congrats on the greenlight, by the way!
EDIT:
Oh, wow. First game over in the Great Wyrm Tangle. I'm not sure if I was doing it wrong or if I just walked face-first into a beefgate, but some of the things in there were hitting for 15+ against my Guardian, and despite 3/4ths of my team having great AoE damage I had a hard time killing everything. I'll go explore somewhere else and come back later...
