The general consensus seems to be that Dreadnaughts are over-priced in relation to the number of hits they score and other useful things like a capacity, and that they are not really good until you have researched a lot of tech that's all over the the tech tree. It has also been stated many times that they can come in handy when you have a low fleet supply or only one or two build slots left, or if your racial tech/abilities makes it easy to make them stronger. Or if you have an Admiral they become better. But for the most part they do seem like expensive and risky buys.
Our house rule to amend this is that DN's roll 2dice and take 2 hits, and War Suns roll 3 dice and take 3 hits, with the number of die rolls decreasing as the unit takes damage, example: after a War Sun takes one hit, it rolls 2 dice (instead of 3) in the next combat round. But what about making other house rules? Giving DN's their own capacity to carry units? I've been toying with this idea, and am currently play-testing it, so here's what I've got so far:
Dreadnaught: Cost 5, Battle 5x2, Move 1, Capacity 4
Stasis Capsules would modify a DN's capacity to 4+1GF. Example: it could carry any combination of 4 GF, MI, PDS, or Fighters, in addition to 1 GF .
L1Z1X Mindet's Racial Tech would modify a DN's capacity to 4+2GF.
Please give me your thoughts, comments, and any other ideas you might have to make Dreadnaughts better.
