“Looking at his win% I though jonnytheg would have been really easy to beat.
Especially when i saw the bad selection of skill of his gobelin and one of his first action of the game (an unneeded 1 dice blitz block).

So i started playing a "bit" more risky than i used to be.
Well i quickly change my mind because he wasn't doing any noticeable mistake.
No more unneeded 1 dice block first action of his turn etc...
Eventually i won but it was not easy.

Still some mistakes though (like re rolling a not turnover block result with his loner ogre and in general unneeded blocking first/second action of his turn with Big Guy).

I'm honestly surprise you do not have an higher win%, but i see you have been unlucky to play some good coach.
I'm sure with a stronger team (like orc/dwarf/undead/lizard, not crappy Pact) and a good selection of skills your win% will skyrocket.
I hope you will have the willpower to continue practicing and not be discouraged by your currently poor result.
Results will come with more game played.
Also watching replay of the best coachs and reading playbook help. ”
