I ran the playtest for Gregor earlier today, And I've come to decide he either needs some Nerfing, or a point increase. Placing him against a similarly costed hero, Gregor will shred him like tissue, and a against a squad, he hammered out 3/4 off them, the last being dispatched by a squad of accompanying axgrinders. While Gregor proved an effective budget beatstick, I think he is too deadly for his current points.
The report is spoiler-ed below. Please note, I had forgotten there was a rule about dealing extra wounds, so the results might be slightly skewed, but it is still relevant.
Spoiler Alert!
Trial 1: Gregor Crookedgear V.S Me-Burq-Sa
Myvra player: Heavyfishcannon
Utgar player: assistant
Spoiler Alert!
Deployment: Gregor is in the lower left corner, while Me-Burq-Sa is in the upper right.

Gregor smells a brawl, and make full movement to the bridge, to meet any foes.

Me-Burq-Sa trots over to see whats happening. He attempts a parylizing stare, but fails.
So, Me-Burq-Sa takes fire. The shot sucessfully hits.

"You Call that an attack? Let the steel of the dwarves help yer aim!"
Gregor charges, and hits with his mechanical strike.He deals 1 wound.

another wound is dealt to the deranged dwarf.

Gregor swings, but misses. thanks to his mechanical equipment, some damage is still done.

and thats enough to hurt the sniper!

Overview.

Deciding the dwarf was getting too close for comfort, Me-Burq-Sa oogles Gregor disconcertingly, paralyzing him.

Thats snipers for you. never could play fair. Gregor is hit!
Gregor returns to his senses, and bashes the Marro, relying again on his machinery.

And Me-Burg-Sa goes down!
Winner: Gregor Crookedgear!
Trial 2: Gregor Crookedgear V.S Me-Burq-Sa Part 2
Myvra player: Assistant
Utgar player: Me
Spoiler Alert!

Overview, from my perspective.

Our forces converge, again at the bridge.

Gregor moves up, and attacks Me-Burq-Sa.

He strikes true, and deals wound! (P.S: A more jarring example of me failing to remember rules!)

Me-Burq-Sa fails to parylize Gregor.

A relentless and angry dwarf charges Me-Burq-Sa mid retreat, and attacks!

I think mechanical strike might be a bit too powerful for the points. It has turned many whiffs into a sucessful strike, when matched with low defense values. Very good for squads!

And this is where I wish Me-Burq-Sa had a similar inability to fail a roll. Paralyzing stare fails yet again!

Me-Buq-Sa also misses his shot.

Gregor Crookedgear does not.

Gregor CrookedGear Wins!
I also did a battle between Me-Burq-Sa and his Romans V.S Gregor and the Axgrinders, but I need to do something now, And will write it up later. Gregor won that too, though. Mechanical strikes a
beast!
