How can you guarantee that every colour pair has an equal amount of lands? That is only possible if you either seed in some boosters more than 1 or the number of boosters is a multiple of the number of pairs you have.The nice thing of seeding is that you actually have to draft the lands, so you get not only the fighting over fixing, but also different distributions because a 4-color drafter naturally is more hungry for mana fixing than a 2-color drafter. I don't mind that What I like about seeding like I suggested is that you guarantee every color is evenly supported. If you see only fixing in the wrong colors, that's a good sign then that your lane isn't as open as you thought it was.
Also, I support only five of the ten color pairs, so it's actually less likely to never see a land in your colors.
I like the fighting over the fixing, but not all players value lands correctly.
