so far i have played is with 2 against me 3 against me and 4 as me against myself. I remember almost all rules(not quest rules though) and do everything as i would do in any game in same place (though playing alone whole game i forgot leoric's heroic ability completely and used some of others feats/abilities rarely)
First Blood: 3 times (with 2,3,4 hero) won every single time as OL though with 4 players got bad luck with rolls and big dude had 1 hp left when goblins got away. 2 and 3 games where too easy .although i played reinforcement wrong every time (just noticed). it wouldn't have effect on any of my games cause rarely heroes got even one down of thous cause placed them far back to starting point hide them end of every turn.
Fat Goblin 3 times (2x2 hero and 1x4 hero)
1 encounter: played storage thing wrong and lost to heroes 2 times against 2 heroes only played it right on last one and face rolled all crops (1 goblin took 1 damage and had one to back him up so not even close to fail)
2 encounter: 2 times i have dashed at right time to entrance with 0 damage taken so luck was with me most of the time and did good blocking with big monster and goblins
Gastle Darion 1 time (4 hero)
1 encounter: heroes one only cause i almost have full deck drawn and spend during that and was bored to block last beacon with big monsters.3 hero killing and get killed and 1 guarding 3 villagers (2 of them almost dead and 1 with full health) most of fight.
1 turn: Heroes had killed whole flesh moulder group with 2 good blast attacks. healer guy (spirit something) charged to room to give stoneskin to palamon but didnt have fatigue for that in first turn.on OL turn i hammered almost 15 damage to Sir Palamon with 1 zombie and 2 ettins with 4 cards used on attacks.
2 turn: all heroes hitted monsters with minor damage except grisbane the slow who used move+ full fatigue move + rest to get next to one of ettin. OL gives other good beating to palamon with ettins/zombies/ farrow would have died but i decided to say that leoric was close to 3 of thous monsters so he was near to dead bed already.
3 turn grisbane hits with all of his might and new axe 3 times and still barely even scratch ettin with good defense dies and when he got big hit used 2 shield card to easy the pain. others tried to do same but now luck to kill even one of 2 ettin's let alone farrow behind them next to 2 flesh moulders (master and minion) and heal card in overlords hand. OL turn i healed ettins with moulder master and heal card. Then hitted with all ettins (both missed) and zombie did finising blow with farrow still left with waiting number ticket in his hand.
Gardinal's Plight 1 time (2 hero)
played roll thing wrong and 2 hero in 2nd part is realy hard with all zombies
Masqurede Ball (first part) 1 time ( 4 hero)
had luck as OL on quest positions. Managed to escort 3 as OL heroes 1. Heroes got all chest rolled blank on black die so the won first encounter
so here are some things that could help heroes bit:
1.house rule goblins only be able to move ones during turn when they are doing something important cause they are too fast to do stealing/escorting/escaping?
2.more health for palamon or better die in 4 hero game ?
3.1 movement action only if carried something but can use dash for 2nd one (dont know if there is rule fix on site already)
give your thoughts and bare in minds that this is what i have thinking cause it seems that most of the time game is too easy to me as OL and i dont want to play game where others dont have fun cause soon i only get play this alone and still win as ol : (
