Plarium I do believe your success percentages on gear upgrades are way off and you are absolutely shooting yourself in the foot and losing paying players over it.  I have made 3 attempts at a level 8 gear upgrade, all of which using hellfire for the maximum available 75% chance of success.  All three failed.  A teammate also working on levels 7 and 8 said that 7 of their last 10 upgrade attempts have failed.   Given the amount of time, materials, and gold invested, this is ridiculously unacceptable.   A level 8 gear upgrade requires 74 legendary invader materials.  Thats the equivalent of approximately 12-18 hours of invader killing if you have double hero and plunder.  I couldn't even imagine the time investment without those two purchased bonuses.  The upgrade also requires 718 legendary standard materials.  If you are up to level 7, I guarantee you've already spent your entire stockpile, so these materials will cost you around 60 million gold to purchase material coffers.  Throw in the hours invested in helheim to earn the hellfire to increase success chance, we are talking a massive investment of time and money.  That's just one upgrade on one piece of equipment.  Now imagine doing all of that several times and receiving nothing in exchange.  It's absolutely infuriating.  To require such a massive investment and offer only a 75% chance of success is unconscionable.  To do so and then in practice only actually allow 25% to succeed is repugnant and frankly quite criminal.  I have heard many players over the last few days talking about quitting the game over this.  It isn't bitterness over just their last gear failure, it is that plarium finally went so far, asked so much, and gave so very little in return that it threw into stark unfavorable light how outrageously expensive it has become to stay competitive in this game.  It also shed light on how little regard plarium has for its most loyal customers that they would require such a massive investment and not guarantee a favorable outcome.  They instead offer up a "chance" with a more palatable success percentage for yet another additional investment - and even then they've fudged the percentages so that the actual outcomes are nowhere near those that were promised.  Only in a plarium game does 100% chance of success result in a failure.  It's a blatant rip-off.  So very blatant that people are getting really angry over it - I mean REALLY angry - and they are beginning to question just how much they spend on the game and just how little they are getting in return.    Our clan has now begun keeping track of our success rates and I suggest others start doing the same. There's a difference between charging a premium price and robbing people of their investment.  This game was already on the top end of premium price for an online war game.  These new gear upgrades with their massive investment and their disproportionate number of failures, have crossed over the line into robbing people of their investment and plarium is going to lose a number of players over it if they don't set this right very quickly.   I don't mind paying for my entertainment, but if I wanted to gamble I'd go play roulette - turns out the odds there are much better than a level 8 gear upgrade.
