Companies like TPCI are often dismisive and don't take constructive criticism seriously.
Assumption.
I've never once seen a representive come on here and justify why certain cards are cut/put in.
1) Who says the representatives that we've seen post on here before have any control over which cards are added/removed?
2) What would it help? I doubt your opinion on what should be and shouldn't be removed isn't going to affect future changes. Many changes have been made throughout the years with no communication from the player base. Why would it change now?
As long as players boycott the set opt for singles instead. TPCI wll gradually get the message and begin to change their ways.
You're wrong.
1) Players, as a whole, have never boycotted a set. There are too many players out there, that it would be impossible to rally every player to do the same thing, like not purchase a certain set. Even if one could communicate to one community online, there are still a majority of non-competitive players that purchase booster packs for their own wants, regardless of how competitive the set is.
2) Players have given TPCi plenty of negative feedback on sets throughout the years. Nothing has changed. TPCi makes the decisions on what to cut/keep and players have to accept it.
One of the main reasons I stopped playing this game was because of the inherit flaw in the game that in most sets, 80% of the cards are not important, not useful, and are just a waste of space. In some sets, perhaps the one mentioned in this thread, it might be 90% of the cards are useless. It does put a bad taste in my mouth when I buy some packs at my local hobby store and not pull enough cards to make the purchase worth it.
And this may be an inherit problem in all TCGs, but I think games like MTG and YGO may not have the problem as much because they don't use an evolution stacking system where the understages play a very little part in the overall game, where the focus is mostly on the highest stage of evolution.
Look at sets like Team Aqua/Team Magma/SP-related sets, and how many cool mechanics were introduced in sets based around mostly basic Pokemon. Remove the evolutions and suddenly 30%-40% of the set opens up for more options, allowing for cooler combos, which the whole game is about.
But back to the original topic.
TPCi has some great representatives that will sometimes come onto this forum and reply to the community. They are some great people. But don't get that confused with the idea of players having any control over how the game is produced behind the scenes, because they have none. And nothing players do will give them access to that control. If players don't like a product, don't buy it. That is the most control they have over a product. Even then, I doubt, even with a huge boycott of a product, that any changes would be made to future products that may already be designed and ready to print months before.
