THIS IS NOT DIFFERENT.
For God's sake. Are people so stupid to seriously not get how this actually works. Whilst there may be a difference in Holo/Prime etc pull rates, this is not evidence of it whatsoever.
Obviously it has to be weighted in relation to how many there are in the set of each type of card.
Now supposing a set had 10 normal holos, and 2 primes/EXs/whatever. And you pull one of each card per box. This means the rate is EXACTLY EQUAL. Even though it is "1 in 3" vs "2 per box" etc. You can get less of a specific type of card in relation to another, simply because there are less OF that type of card. It doesn't mean the pull rates are different between actual specific cards.
Here is some food for thought: did anyone know that the FA Reshiram/Zekrom in BW are MORE COMMON than the standard holo versions? Because you get one of each per box (1 per box! sounds rare, right). But that leaves less than 1 per box spaces left for the regular holo cards, so they end up LESS than 1 per box. You would get say the FA Zekrom, but possibly no normal Zekrom (ignoring RH), or no Klinklang, or Zoroark, or Serperior or whatever.
No doubt whatever it is with the EXs, whether they truly are rarer or not, people will misinterpret. You can only compare rarities if you count the TOTAL numbers or holos + 'chase' holos in the set, and work out the rarities IN RELATION to the amount of each in the set... it is like saying getting a 6 on a die is rarer than 1,2,3,4 or 5 because they are 5/6 in chance or 1/6 chance. It doesn't make 6 an ultra rare, even if it did happen to have an omg cool shiny border.
Collate data of card pulls for EACH card then you will see what the difference in rarity is. You should realize that as the frequency of "CHASE" holo card pulls go up, the amount of "NORMAL" holo card pulls goes DOWN such that it no longer is 1 in 3... other than with primes of course in the set which took the RH spot as mentioned. If you get 6 EX/full ART/shiny whatever, then you are only getting 6 "NORMAL" holos... doesnt sound that common given how many there are
I'm seriously angry. This is my final post on here. ragequit
