On the last day of the beta, since I had nothing to do I started exploring over high level maps (map lvl 120, i was lvl 60), there I found a wounded guardian, so I talked to him, he needed for me to buy him some time while he was recovering, so I took the quest and protected him from a few waves of monsters until the timer was out, he rewarded me with a level 6 exp card. I’ll post a video of the quest later here.
(Try to ignore the spanish dialogue xD this is a fragment that was recorded with TeamSpeak ON)
I feel that this experience was a lot more rewarding than if the quest was marked on the map since I was the one that found the soldier, I didn’t need for the interface to tell me where he was, I wasn’t even searching for him, he was there alone and afraid and I helped him to survive
this is why I love that all quests should be hidden. I feel that if you have quests marked on your map or flagged over the npcs, it makes no difference from grinding.
