Ahhh, ok. But seriously they are kinda the same, they take pir stuff. Devours it and turn it into un recognizable goo. The big diffrence is that tyranids are bad-ass while ward absoulutely isn't...
ummm... why? Why are the ultramarines OP do explain your self. I mean we aren't even talking about grey knights atm... where do you people get these OP ideas... form the TT rules? Cause if this is true that most of you reflect your opinions to what happens in TT then you are waaaay off track and should start to read the lore and watch the numbers more carefuly and not just who usualy wins on TT. edit: damn forgot my quote completely.
why not both? Fists are awesome, but they are even more awesome when standing next to an Ultramarine.
