Lately i noticed that i dont receive the gold i'm suppose too, warp, chest and even in game but if i,m doing an event its seem fine, yes i open them when i,m far in mission but the drop of an 8h warp dont even give me enough to get 1 level on my crusaders

what u mean ? are you saying that if i'm having an hard time to kill mobs it drop less gold ? if that is whats the point to stay forever on a mission,because before i have enough power...a year will pass btw wasn,t able to finish any mission for a long time i was wondering even if i,m stronger and do it again its not easier ....feels like if i get stronger the mission follow my strenght

game is exponential. sure monsters drop more gold the higher you are but the costs of one level or 25 levels or whatever also go up the higher you are. and the higher level someone is the higher it costs to level him even more.
see for yourself, level someone, anyone, as far as you can get him, sit still and time how long it takes to get enough gold to level him 25 more, do that, and time for the next 25. you will see that second one is 2x or more longer then the one before that and 2x more then that for the next and so on. If you are advancing then you will be earning more and that covers that time, but you reach a place where you are tanking and not even killing one monster and you are getting no gold till you kill someone...

Try reseting. Its a Huge part of the game. Gives idols-> which gives power.

tyvm will try that just by curiosity how long does it take you to finish a mission...more than 5 days ??

For the most part, you should be resetting every couple of days at the absolute most. If you can't do that, then do some free plays to bring up your idol count. I usually do 2 resets a day unless I am shooting for the hardest crusades.
