Guild Wars 2

Anyone knows how long it will take to get 12 commendation medals?

According to http://www.guildwars2hub.com/guides/basics/complete-guide-guild-missions:

“First and foremost, the rewards for completing Guild Missions are generous. Not only do they have a chance of dropping a precursor for everyone in the guild who completes them (we can only assume it replaces one of the two items you’re rewarded with) but they also provide 50 silver, 2 Commendations (another new currency) and two rare weapons or armour (though loot tables suggest this also includes exotics). The potential then, once you have all five Guild Missions unlocked at all tiers, is to earn over 4 gold per week and 12 Commendations (I don’t believe Trek offers Commendations). In addition to this, your guild will also be rewarded with incremental Merits based on the tier of Guild Mission you are participating in.”
