That's a  valid  point👍

Sorry  about  the  image  size I  just  copied from  my  FB  post  age.  You  are  correct  the  images  shown  are  for  the  special  sets.  There  are  standard  levels  of  some of  the  gear.  Mostly  you  are  correct  because  there  are  a  million  ways  to  play  the game.  My  first  KD  was  102,  since  then  I've developed  a  style  using  three  towns.  I  use  three  devices,  and  it  works for  me.  These  are  things  that worked for  me  over  time.  As  for  the  math  calculations,  I  will  stand  corrected,  thanks  😊.

Sorry - should have been clearer. The 1052 and 916 refer to the amount of hero juice needed to make 1 hit in each case for the Hero without and with gear respectively. Obviously, Invader and Hero knowledge play a big part too.

When needing to score points more than getting gear I have used enough Hero juice to kill an Uber with a single enhanced attack but the quality of the rewards are much lower as you don't get the repeat attack bonuses.

If wanting gear I do single repeats until the maximum bonus is reached (600% for me) and then hit with 1 enhanced attack big enough to destroy. Tried doing single hits all the way but no real benefit and runs the risk of a poacher stealing your kill. 😀

Regarding invaders, the amount of juice used per hit is governed by knowledge (both hero and oracle) and by level of gear. The effectiveness of the hit increases by 15% up to a maximum determined by level of gear and knowledge, subject to an overall max boost of 600%. (I hope this is making sense). If you have the juice and skill to kill an Uber in 1 hit you don't get the benefit of the boost(s) so it costs more in juice and the rewards are not so good.

Like pipkin, once I have the max boost I try to finish the invader off with 1 x enhanced hit as it reduces the chance of someone stepping in and finishing it off.

My enjoyment of the game improved when I joined an active clan, whose members were happy to share experience and I also earned gold etc. in Clan events.
