is Gem Digger worth the gems? because I have the intel one at max which is 75% but it takes an average of 6 taps to get 1 intel, it's totally useless. First of all the % mean nothing because I should be getting it 3/4 times not 1/6, 2nd my Gem Digger is at 20% so I should be getting 1/5 instead I have to tap constantly non stop for a whole 2 mins to get 1 gem, my henchmen beat up more enemies than I get gems. I am asking if this is worth it because i want to know how high the gem digger's % goes so I don't waste my gems.
