I find that gvg, like explained from the GM's everytime they open the event, is a event where guilds fight for Supremacy. Which includes training for your members, strategy and teamwork building. The Ecoups and gvg certs are rewards enough. When RIP wins against a huge guild and wins a gvg despite all odds. that is satisfaction enough, I agree with nines, your posting this out of greed.
And Don't forget that even if you did win 8 gvg certs you get 1 Ruck by itself, and it goes directly to your Guild Leader, and it is His/her choice whether to keep the ruck or to give it to another member, or Sell it off. So yes if your lucky your guild leader will hand out the rucks for loyalists. So yea, now even when the rucks only have diff color and no extra stat + I don't see them being circulated around. All the more reason for your guild masters to Keep the rucks, if there were benefits as such.
