Nope. I'm not trolling, I understood your point, it's just a bad point with flawed logic. You wrote the post moaning to EA about pack luck not me man.
Sure, EA could code in that logic, but then you'd have players immediately take advantage of that mechanic. What would be there to stop players buying up a bunch of cheap/bad icons/heroes to then maximize their chances of packing a good one because of the pool sample size of 'owned' icon/hero players in their club, then just straight up selling those players again after having completed the pack. It would be unfair to the rest of the player base.
It's not suspect at all. You're posting this acting like it's some sort of conspiracy against you. Face reality dude. If this was a major issue, wouldn't there be a tonne of people complaining in the forums about packing dupes like you have?
Here's the reality. You did a gamble SBC that only garunteed you a hero player. That's it. It didn't promise not to give you a dupe. You also did the SBC knowing that this was the case and still went forward with it. Despite this, you're upset you packed a dupe and are now complaining about pack weight being fixed somehow and want EA to change it for you regardless of the knock on effect that may have.
There were also a tonne of other people today that did the SBC and didn't get a dupe. You had bad pack luck this time around. EA aren't 'out to get you'. Deal with it.
