Whats the meaning of upgrading... if

while the enemy get 3x stronger if i upgrade, i just finished a dungeon and made the leader silver and 2 others silver and next dungeon i got beaten more easy, wth is this programming? also looks like enemy’s gold rate is 2 times faster. he spamming so much i cant even build up a minion train (minions that buff eachother) and even when my minions are 3 or 4 lvls higher they get killed as if they are lower. explain this to me?

we players may not cheat in online games (also i dont even want to cheat, thats why i have still not bought a bundle because then i pay for win) so why is the npc programmed like a cheat?

also many minions have such a very strong description for what they offer but they just get nuked like its nothing.

To spend more money to upgrade more of course!
