First,  I accept that "rewards" such as cancelled marches, jeweler's tongs and stamped paper are useful BUT as a player levels up the number collected is in the hundreds. Low level tongs are useless when reaching legendary level. Stamped paper is seldom used in a active  citadel holding.  

Second,  After achieving the current VIP maximum of level 15 VIP points are worth nothing (though 500  and up are  stored).  The average number of times that are worthless VIP  points  range from 5 to 15 depending on the  the level of the assailants.  When added to the above mentioned "rewards" more than  35% of assailant attacks  are only worth the experience points.

Lastly, Plarium  administrators need to  re-think  and  update the program as it relates to  rewarding higher  level players.  Either by restricting the type entirely at achieved levels or substituting with new rewards.
