Warhammer 40K Tabletop XIV: "Pray for 6's!"

[Tehnar]

I am new to all this, but I had a game last night against blood angels and found the furioso dreadnaught fairly underwhelming (especially compared to the assault marines with the sanguinary priest).

I assaulted it with a unit of trukk boyz, it killed 1, and then the Nob powerklawed it and it went puf. I think it was one without any upgrades, but 3 attacks doesnt look very frightening. Unless we are missing a rule or something.
