Well, I just looked at the Underworld team roster and I think, just adding one makes them to powerful.
That would mean Underworld could field two big guys. That might be okay with the Goblins or the Halflings, who, on their own, couldn't even stand first half against bashers.
But Underworld has Skaven Throwers, Blitzers and Linerats too.
They are all pretty quick (MA 7), the throwers are quite decent ball handlers and even the linerats (ST 3) can handle a block or two.
A 16,67 % chance that a Skaven wouldn't hand over the ball to a Goblin might be a hindrance but it's not that bad.
So a Troll flinging Goblins down the field in addition with Skaven flinging the ball right after them is quite some weapon, I think.
Having another large beast that could tear through your opponents ranks doesn't sound fair to me.
Maybe if you
replaced the troll with the rat ogre?
You could remove the troll completely from Underworld roster and replace him with the rat ogre.
Or maybe you could add a house ruled skill to the Warpstone Troll and Warpstone Rat Ogre, like "Rivalry"
House rules wrote:Rivalry (Extraodinary)
A player with this skill loathes players from his team that are a different race than he is and are as strong as he is. He absolutely refuses to be on the same team as the other player. The player can not be hired if there is another player with an original stat ST equal or higher than his own original stat. No stat increase or decrease will be taken into account when this skill is activated.
This means you could either hire a troll
OR a rat ogre, but never have both on your team at the same time.
So you couldn't field the troll after the rat ogre has been injured or sent off, but it still gives the team a little more variety.
Since we only look at the original stats, the troll will be the only other player to activate this skill on the rat ogre and vice versa.
Opinions?
Wouldn't this thread be better in the
house rules section?
