The clones are getting out of hand. I'm getting tired of meeting "level 20" players that know every single answer. Significant lack of fairness for those of us who play honorably.
@yodaveth: But imagine what would happen if there was no energy limitation. Some people would do nothing else with their lives but play, and the top positions in ranking would be occupied by the players with the most time in their hands, and not the truly best players. When you become a level 80 or so, the energy you gather is more than enough. Also, the energy system is better than the game supply system that existed not long ago, but playing without limitations has its risks.
Those of us who play through Kongregate and not through Facebook lose so many privileges: extra games, boosters and coins sent by friends. Thanks to those extra things, a lot of Facebook players who are worse than us seem to be doing much better in rank. We are fighting against the odds, so we accomplish quite a lot in comparison.
@96puduhs: It's not 'fake' - they've just used a 'select a subject' booster, which allows you to attack a castle with questions only from the topic you know the best, thus giving you more chances to win. It's a really sneaky booster and helps a lot. I'm usually attacked with sports and math, which absolutely drives me insane since I suck at both.
