Should've done the math..
I guess I'm just unlucky then
Also may I point out you did your math in a week where all of the 4 recent releases had potential.
I've more then once had packs worth just over 1000 so should I go with chance or guaranteed? LW is guaranteed because I have faith in myself that I could reach a minimum of 4-5 wins, where as packs don't rely anything on my skill or ability and as your math suggests I'm very unlucky..
Also how do you know that % of time you will get a R or U? Cos in a 20 cred pack I hardly ever get a rare..So 50% (to me) seems like a bit of a stretch
Look at a pack pull thread. Pretty much everyone agrees the rates are equal. There are times I've opened 5 in a row with rares, and others where I've gone 5 without them. The danger in saying what you did is that your sample size is too small - only 3. Increase sample size and you'll find the rates everyone claims are there.
By my recent sample size, I bought 1 pack and got Matriochka from a 20 Cred pack. I guess she's in 100% of packs. 3 seems like it should be nice, but we've all has bad runs, and UR pack pulls are no exception.
Also, saying it doesn't count because all 4 are good makes no sense. I am using pack data from the week you are claiming it's not worth it. Not a hypothetical pack week. Regardless, even removing 2 more, do you really think it's going to cover the entire 49% difference? I'll give you maybe 5%, but that's still a hefty bit to be off.
As for LW - I still want UR to change it so I can simultaneously choose my cards at the same time, eliminating the need to switch my intended Leader halfway through and giving me a worse deck than I otherwise could've built.
