As far as the compendium goes, I have 1 issue with it.
...and you go on to cite a recent rulings controversy.
Six months. Not six years. Not 12 years. Not the entire run of the game.
Being new to the game does not invalidate your opinions, but it does require you educate yourself. I don't know you, but imagine you were doing something well, perhaps extremely well, for over a decade (work, a TCG, some other hobby, etc.).
Now a fairly new customer comes in and says you do a questionable job because of mistakes made by your boss, and poor communication between your boss's boss, and because your bosses decided to reverse a decision made over a decade ago. That's the rulings situation.
WotC, the company that previously held the license for Pokémon TCG card outside of Japan and handled everything for it, wasn't willing to pay enough to retain the license and rushed out the sets they still had the rights for. This was when the first "shuffle only the revealed" cards translation error may have arisen (I need confirmation on that, if anyone knows the Japanese text for
Fast Ball).
This was nine years ago. They also made some incorrect rulings at this time that were reversed by under what became TPCi. WotC was known for trying to use Pokémon as "Magic Jr." and even cut the 15+ age bracket from organized play (not that they even gave us a lot of tournaments); this was undone later.
Just over five years ago, we got
Quick Ball which had similar text, and similar rulings were made about revealed cards and shuffling the deck. Did we establish that the card didn't work that way in Japan? I know for
Random Receiver it has been confirmed different? I ask because of the issue with modifying Bench damage.
Before I get to that,
Random Receiver was released outside of Japan in May of 2012. That's this year, shortly before World Championships... so the ruling error based on older errors, including errors from those no longer involved in the game, was actually caught just a few months later.
As for the whole "adding to Bench damage" thing, the problem there is that the Compendium hasn't apparently been updated, plus the fact that this change in the rules still is a bit annoying. You could not increase damage done to the Bench with other effects in the Pokémon TCG since the first Bench-damaging cards debuted in... was it
Fossil? That was the second expansion (third set) of the game in the U.S. and I could be wrong and just forgetting something from one of the two older sets.
It didn't change until a ruling on some obscure combo came into existence after the release of
Black & White in April of 2011. I think we've had one other similar combo also contradict the ruling, but for all older cards, for now, it still seems to work this way. I think. Yes this is a mess... but it is sort of "the" mess with no older, similar issues.
As for the communication thing in general, translation is an odd thing, and transliteration often a "bad" thing (where words are translated "directly"). Japanese and English to not correlate directly to each other with sentence structure. So even if we have fully bilingual employees translating and testing cards, it is easy for situations like a
Random Receiver hitting a Supporter right away to not register as issues.
Better communication would help with this, but it isn't like a bunch of English speaking (sometimes not even English speaking) players can directly communicate with the Japanese speaking staff that issues rulings... and since the ways the languages work are different, even dealing with bilingual representatives can cause oversights.
