Well I am going on the idea that a list is stored of all player activity already, and there has already been specific look ups designed to make lists of specific faction tag online time. This I am under the impression that
creating a new look up would be as simple as replicating any of the others but just changing the faction tag.
Thus I am under the impression that creating an activity tracker for a specific tag would be quite simple and
not at all time consuming.
If no... I am sorry, please say... "sorry son it would take 3 weeks of dedicated dev work".
I mean whilst I love chasing people around on skype/forums/pm/hunting-them-down-in-person couldnt extra factions just be added to the tracking relatively quickly by Cannon?
However, if it would only take a few mins and even less time if they were given a list of everyone who wanted it and it could all be done at the exact time and thus take even less time.
