I actually could imagine a "walker" category for each race that could be balanced against each other. I don't expect the balancing in this game be match the tabletop, and I don't think it'd be too much of a stretch to make things like war walkers, sentinals, dreadnaughts, killa kans/deff dreads, defilers, etc, function inherently the same.
But the Dreadnought is a past-death machine, which is fundamentally different from things like War Walkers, as has been discussed quite thoroughly already - and as such, the two should not be compared. And this game is not meant to be balanced in the traditional sense. The developers made a wonderful quote about it being "Unfair, but equally unfair to all"
Why I mentioned it from the person I quoted, was the odd one out. If they needed to add for the sake of balance fine, but needs to be put in right.
I'd say do it. Make them only usable for Guardians (who also get to use the special/heavy weapon platforms) or have Guardians spawn with them. Put some of my thougths on paper over here.
and i would join you brother. 2 dark reapers sitting on a war walkers shoulders bringing the kiss of death to our foes
Should be in the game IMO. Assuming they are going to have Dreadnoughts and Wraithlords then having a more shooty open topped walker doesnt seem too much of a stretch to me. Stylistically I would think things like war walkers would make Eldar visibly stand out on the battlefield as its a good representation of Eldar technology. I know we would have to have a fast skimmer and as cool as they also look they do not stand out to me as being as different to other science fiction vehicles when compared to war walkers.
