Guild Wars 2

Hello community,
I just got a crazy idea. I haven’t thought much about it but tell me what you think. Imagine you could have guild “Achievements/Titles” by letting the guild leader, or anyone who got the permission from the leader, choose some “Guild Dailies” like:

-Do 3 dungeon runs with only guild mates
-Help lower non-level-80 guild mates do 5 hearts/skill points
-Do 5 Guild-group SPvPmatches
-Clear 2 Meta-Events with a full guild group
-Capture 5 Camps/Towers/Keeps being in a group of guild mates

And so on. Then after you have finished it X times you get a title like Guild Helper/Dragon Hunter/Guild General/ or whatever the guild leader has chosen for the specific “help action”(There is a default title which can be changed by the leader). These titles are only for the guild so only the guild members could see it. This would show who actively helps the guild and make it more fun to help out others. The problem is the reward. I thought about a certain little amount of Exp/Karma/Silver when you get your guild daily. But i think as you help you get enough rewards so i don’t know if a reward is really necessary.
Tell me what you think and if it would be possible to implement it or not without too much trouble.
