Personally, I feel that Orkz receive too much scrap. As soon as Ork player gets 2+ Towers going, it makes it not only pretty easy to keep every squad you have scrapped up quickly (especially if you save them, as you should), but also means Orkz have huge piles of scrap always laying around.
I think the towers should receive a nerf to their scrap generation rate - especially since, late game, you can literally convert them to vehicles for 50% cost.
This doesn't even consider all the scrap that appears on the battlefield too...
And then you have units like weirdboy who can always remain at full scrap shield, basically, because of the rate.
When I play orkz, I always feel inundated with scrap that I can't use it fast enough to get rid of it.
How does everyone else feel about it?
