I'm not a part of WoTA, but I figured my input might be welcome..
The "turning in scales for points" is seriously flawed. One person can go to green level one day and farm 20 scales in an hour. Someone else can go right after them, for one hour, and get 3 scales. Scale count does not always reflect the amount of effort a player has put into farming. Even if you are giving an entire group points for getting scales... Ive been on runs where we have farmed 40 green scales in an hour. I've seen similar sized groups get 5 scales an hour. There is a HUGE difference in points here...
I believe that HOURS spent farming, not scale number, should be taken into account. Of course, this would require trust. I guess it would require keeping an eye on guildies if they seem like they're spending more hours farming than the number of scales they turn in - if this makes any sense? But i think both number of scales turned in and, most importantly, hours spent farming should be taken into account...
