I see it's been two months now and there is no fight kings going on in the timed challenges... All I see is the gold, food, breeding etc.
Is fight kings stopped because of the new PvP release?
Will there be any timed challenge based on PvP in future?

i think we have it recently - not 2 months - and i see no problem having it with the new pvp system , what we will not see again is stealing food unless pvp allow stealing again

Shield implementation needs a serious rework before Fight Kings can be successful. Then again, when has a cr**** implementation ever stopped SP from go forward with something?
