I'm relatively new to the game, although I've been playing it a lot recently... I've noticed there's a common belief that the goblins aren't that good, or at least that the goblin rush advantage is not as strong as their frightened disadvantage. I'm not actually 100% sure I agree with this sentiment, but on the other hand I haven't really played enough games with the goblins to tell for real.
I got the following idea for a house rule to improve their rush a bit, and I'm looking for opinions from people with more games playing goblins under their belt.
In addition to all goblin units being able to move two hexes and still battle, make the enemy lose one step of bold during the round in which the goblins perform their rush. In most cases, this would allow them to battle once without the possibility of a battle back. Even better, the units that could counter this best would be the dwarves, their nemesis (with support).
Minor alterations to this might be requiring the attacking goblin unit to have support itself (to simulate a horde of them attacking) (you could also limit it to just one adjacent goblin, instead of full support), or requiring them to move at least 2 hexes in order to be able to trigger the rush.
This would be a new mechanic as far as I can tell, and would require the opponent to take the goblins into account when he places his troops, just as it must be done when facing dwarves. Also, as a more or less single use ability, the impact of the modification probably wouldn't be overly dramatic.
The only abuse I can think of straight away would be a situation where, on one flank, the goblins rush their enemy. On his next round, the opponent doesn't have suitable cards to fight back, and the goblin player moves them back two hexes again on the following turn. Whether this is abuse or tactics is another topic for debate though
