It seems I have to wait for the final version and hope that there will be a very-very easy story mode.
I save sometimes after each combat round before I attack in the hope of improving the dice chances. But in the goblin village 4 heroes, Halsin and 15 Golbins as opponents?
I fought for 45 minutes and only 3 goblins are dead! How many hours do I have to fight?
I'm only alive because there's a door next to me and every now and then I send a hero into the next room to heal himself.
But my health potions are running low and there are 12 goblins left. It is frustrating! Of course you can see fights as puzzles, as riddles ... but fighting for hours is so boring.
SPOILERS!
Not sure from which side you are fighting. If you came out from the inner sanctum its gonne be tough. Best option is to run and gun if possible. Fight the ranged guys first.
If you fight them from the bridge side, pull them out and funnel them on the bridge. A group will get stuck inside next to the gate. Have one of your chars flank them. (hard jump or misty step to below the bridge and stealth move them to the upper part of the camp. This will take alot of rounds, but you can lure the goblins to the upper part by stealthing the bridge team and unstealthing the flanking character.
Now if you have time to prepare you thin the herd. You can kill the two humans in an earlier encounter, you can kill/disperse the group next to the townportal, the sleeping goblins you can sneak kill without triggering anyone and you can poison kill/damage a big group once you find the location where they drink from. This leaves about 8 to 10 goblins/others for the fight. Now position your team on the top levels (easy if you have cleared the townportal/waypoint location) and use ranged to snipe/ambush the remaining goblins. Use the goblin monstrous manual tactic, shoot and hide every round and it will become easy
