Confidence is everything
You have 70% of success... failed
You have 75% of success... failed
You have 85% of success... failed
That is the reason why I haven't bought any hero energy this year. Whether trying to update my shaman or my hero gear, the odds are tweaked without a doubt. Not the first time that three out of four upgrade attempts fail, and mostly on the day after cvc, but that shouldn't make a difference if this were an honest game. Throughout the years I have noticed many times odds are tweaked on the days usage is large. Five years in a game is enough to notice this.
And even IF it were not tweaked, the thought that only about 75% of my money can improve my stats is pretty disgusting. Same reason I am not buying any Helheim fire. Have you ever estimated how much you need to get your shaman stats maxed? Oh and that doesn't count the odds in yet.
And aside from that, checkpoints in killing invaders events can only reasonably be achieved with one-shot kills that hardly bring in items or jewels. So more waste of money. Come to think of it, all of invaders has become mostly a waste of money.
I know, I have been fazing out of this game for a long time now, but I had a lot of gold, had some strong victories and after that Paladins has kept me in. I'm also no longer actively playing my other accounts since x-mass but obviously I've been emptying their treshold as well. Slowly moving towards the exit.
When confidence is gone, the money no longer flows.
