i am trying to find out or hear about your preferences what to do about the option to be able to combine cards. i see so many dominions and greater now, it almost seems unnatural. here is what happened to me: i took a cheap a half angel 3 (500 spirits to redeem) and tried 22% chance to HA4 and failed. fair enough, so i combine 3 cards to a 60'ish% rate and fail again. got greedy, i say to myself and combine 4 cards to a 96% chance and fail again! then i redeem 3 more cards coz a little over 1500 spirits left.
first card +1 at 22%
second card fail
third card +1 at 20%
i failed saint 4 with a leader card four times in a row (3x100 gems added and failed the 4th time without gems added.)
and then failed saint 5 three times in a row!
all luck you may say and i agree. however, what are the odds to fail a 96% chance? they are a lot lower than failing a 60%'ish chance very slim and even slimmer than succeeding 2 out of 3 cards at 22% and 20%. or how about failing 70% 4 times in a row!?!
so i start to wonder if some heroes from some players are more likely to go up or others are more likely to fail. if the "% chance to fail" is not another illusion. i wonder if it's not predetermined like guild chests, tavern, and all other shuffle chances.
