So the trick to win battles in GE L5 is to stack defender potions till your defense boost is high enough to win most of the battles ... hmm .. this way it don't feel as "FUN" for me and it's, like TARS said above, not something you can do endlessly... defender potions will be all gone fast.
I like to see coming up attacker potion for defending army, or better a potion that boost both attack defense at the same time
... OR ... Inno changing the settings so that not one kind of potion can be "stacked" anymore and NO units of HIGHER than player's current Age can be used to prevent cheating ! Then they please also lowering the boost to a something less insane !
If I look at the numbers now for SAM :
GE1 : 110% - 120% / GE2: 120% - 135% / GE3: 145% - 160% / GE4 : 278% - 458% (for GE4 = ca factor X 2 (278 x 2 = 456) [ boost for attacking army]
GE5 : 345% - 1697% (= factor almost X 5 ! - 345 x 5 = 1725) [ boost for defending army]
The factor for the negotiations for GE 5 are even more insane, X 7,8 !! (negotiations in GE4 : 4 - 9 ! )
Are the GE5 rewards at least 5 times better than previous GE levels?
It would at least be more fun IF you get a fragment of Serpent and/or Forgotten Temple, even if you could ONLY win 1 encounter !
And please Inno, LOWER the unlock cost to open this 5th level drastically ! Or implement something like this (example!) :
That a Guild can pay the unlock costs in 4 parts, like encounters : 65 - 68 / 69 - 72 / 73 - 76 / 77 - 80 .
This way Guild treasury don't get ruined and guild and players make it like a new goal to go for (working up to reach last part of GE5 after a longer time).
