This will actually lead to switching to luck/farm gear and picking 500 trophy players as targets. I don’t think this should be stimulated at all, to raid 500- trophy players.
It’s all a matter of luck, this mission of successfully opening chests. Let me explain, with 25% (actually even lower due to pro pal and pro gear) failure rate on first chest, it’s abnormal that during my first 5 raids, I was able to gain 2 chests (for the record, all 5 raids I reached COF) . And it’s not the first time I get this mission. All times I needed 10+ raids, while wearing 8 pro items and a pro pal.
With 8 pro items and a pro pal it’s 18% luck. When we apply the formula 25%x(1-0.18) it leads to 20.5% on a failure on first chest. So actually pretty close to 1 failure every 5 times. Second chest failure is also less than 50%. when you need more raids than chests to be opened for the mission, I say not for nothing that missions should not be determined by casino elements (It’s up to the wheel of fortune how fast you progress).
You can call that bad luck, I call it a bad random seed, since this should almost never happen that multiple times in a row, first chest leads to a failure. Sure… Daily mission you have time for, all day to accomplish it. But luck should play minimal factor, it should not be that one needs 3 raids, while another unfortunate one needs 10+ raids to achieve the mission.
It’s definitely not hard to be successful 9 times without wasting gems, but missions should be based on skill, not on luck or picking much weaker opponents.
Better missions would be “break the gate of opponents x times by using matchmaker” or something like that. At least a player is stimulated to actively raid.
