This is a card forum and apart from direct word of mouth, is probably the biggest platform for this hobby. It is my guess that ESP keeps tabs on it or at least is in communication with others who do. Therefore constructive feedback (positive and negative) has a direct link back to the company.
As previously mentioned ad nauseum, master set collectors are all but gone, IP collectors are hurting, and players HATE signing cards now. Card collecting has changed and we need to roll with those changes, but at the same time it is imperative that we try to protect what is really important. What will hurt YOU as a collector is losing a community to trade and buy/sell with.
Personally speaking I have collected enthusiastically for 25 years and am still here through thick or thin. I don't want to move on I want the product to suit as many of us as possible and be attractive to new and old collectors alike. Offering constructive feedback shouldn't be seen as complaining for the sake of it, but a sign that people actually care and love the hobby and are offering advice for it to improve. All good companies depend on customer feedback to survive. And asking all naysayers to 'move on'...really? Be very careful what you wish for.
Would ESP have released no. 1s without 'whingeing' - doubtful
Would ESP have numbered their hits without 'whingeing' - doubtful
Would ESP have included a case hit without 'whingeing' - who knows?
Would ESP have lowered their price this year without someone 'whingeing' - again who knows?
Whilst I appreciate your positivity (really), I believe constructive feedback is not petty and has a vital role to play in this hobby.
And for goodness sake we only know two card sets in the upcoming release; no one has actually flamed anything yet.
