I think the rewards overall were pretty meh, but they were also easy to get (progress-wise), so I guess you have to balance that in your voting; it's also only a 1 day contest and that plays a part as well. My biggest gripe about the rewards is for the rank rewards - stamina items are absolutely more valuable than gold chest items, yet 1% gets stamina and the top 10 gets stuck with gold chests.
I love the idea of guild contests. I thought it was awesome when you did your year anniversary in DS (the Bizarre Bazaar Birthday Bash!). For that contest you gave points to GW and Crypt (Fortress here) tokens earned. I think something similar would make sense (thematically as well, since those are both guild-related content).
[Actually, on a semi-unrelated note, some contests that you guys ran back in DS haven't showed up here yet - things relating to gold spending/earning and token spending/earning. Are those ever coming back? They were an interesting change of pace from the usual stuff.]
I am curious since this contest is a 1 day affair and run on Thursday (usually contests start on Friday), if that means we'll be getting our typical solo contest this weekend as well? Hopefully yes ... cause I like "free" stuff
