Well, me and my ultras are on the defensive again then... (and seeing as our gun lines have been nerfed since the last time I played, that's one defence outta the window straight away)
I got back into GW a few months back, and having had all my old stuff thrown out or swapped for beer tokens (and occasionally beer itself) and instantly chosen ultra's, I'll explain my reasons.
1) Me and my mate needed a copy of AoBR, he already plays orcs, that left me with marines. I used to field Blood Angels back in the day, and still have a soft spot for them. So what made me do ultra's? To be honest, the colour scheme. Not the blue and gold, but the blue and white. Looks clean and cool. I decided against BA mainly because I think it's a little silly to run around a battlefield in bright red costumes. American war of independence anybody? (I know the Ultra's are traditionally bright blue, but mine aren't. They're a very dark blue, FYI, so ner
2) They are the most versatile army in the codex, most of the others have a theme and a playing style around which you base your army, Blood Angels = CC etc, which I didn't want, one game I may want to be able to tailor my marines to be an all out CC army, the next I want to be able to stand on my baseline and pour blast markers on my enemy, or some mix of the two. The best chapter to do this is the ultra's. Hell, they literally wrote the book on warfare.
But tbh, I'm bored of them already. I'm almost speed-painting them as I just want a playable army. I'm gonna collect to 2000, maybe 2500, then switch to Guard. Whilst I'm doing that I want to do some converting, so I'm going to go to the most obvious place to do some conversions, Chaos (always fancied a pus-dripping nurgle army, or a tentacley* Tzeentch host).
Bugger. That didn't go as planned. I didn't convert anyone to loving the UM's did I?
*There is no way to spell this without it looking wrong, which is appropriate I think.
