What about new mission mob's? You haven't mentioned if there will be new mob missions added, such as mob that can found by the 100's if not 1,000's on calypso like:
Ambu,
Chomper,
Drone, Boorum, Berycled, Bristlehog, Cersumon,
Hogglo,
Kingfisher, Legionaire, Maffoid, Phasm,
Proteron, Trooper, just to name a few,
mob in bold are my personal preference
I don't believe every new mission mob has to be rewarded with attribute tokens if there is some limit to them, skill rewards will do fine too, or maybe less tokens & more skills. But I do believe almost every mob should have a mission. New players and lower lvl players will finally have an incentive to grind out a greater variety of mob they can handle with increased skill reward for doing so, and mid lvl players will gain extra skills for grinding out a greater variety of tougher mob.
I started playing in 1st quarter 2010 and seem to recall only a few, maybe 4 mob added to mission's since then (Rex, Levi, Trask & Shinkiba come to mind, maybe someone will point the real total added since then), But wouldn't now be the time to add to the missions with these new changes?
BTW, I think the new system has good and not so good points for all involved, but overall I think not as bad as many may have predicted it to be, gives us lots to think about.
