While I agree I must question how much of a power jump I actually gained from my fragments. 150 isn’t a lot after all, it’s not GAME BREAKING and I won’t be winning all PVP matches now when my Maven needs 450 more fragments to next star instead of 600. I could star my 4* Ghoul up though!
If I was on the losing side of this, i.e. didn’t get the deal some others got it would certainly sting my eyes but I wouldn’t claim it has created a power gap between us. It’s a one time deal, I’d accept the power jump argument if we could buy the same bundle over and over again.
(I played another game before where a similar thing happened: some players got a deal that was obviously a glitch*, but in this case they could buy it again and agan and again and this was during the launch of their most OP character ever! A couple of hundred players managed to max this character out in a day which led to a complete power change in PVP. That the developers took a good 8 months to fix the OP character didn’t make us any happier)
*the developers fixed the glitch in an hour and said “omg we’re sorry!”
