It does in no way infer that I am not knowledgable of how to play that game, the only facts here are that you and I have different opinions. Like I said, I cannot remember encountering an enemy with cards of similar rarity, but I always have a hard time with those who have their decks filled with top-notch expert cards.
If two different neutral cards have identical stats and mana costs, but one has one or more effects added on top, then the other card is simply inferior. So there really is something I don't understand, and that is you ignoring things like these which you cannot deny are facts, and still defending the game's non-existing balance between basic cards and unlockables. I do not deny that cards within the same bracket and rarity are intended to be balanced, and I do not criticize that certain balance.
Those legendary, epics and rares all exist for a reason (and they are stronger for a reason), and so do basic and more common cards. And people with totally different unlocked cards are not matched with those of who have the same stuff unlocked and the same skill, even if that was possible. My opinion is that this is Blizzard trying to be economic. You simply cannot define a F2P game as balanced, when dudes who put feed the machine with money have simply better cards than poor dudes or ones that do not feel like spending cash on a savegame.
If you feel telling someone that he or she doesn't know Jack about something, then make bloody sure that you are right about it. Hence it may still not be polite, as a remaining possibility of that being wrong is a possibility of having rushed out an insult. So congratz, you are the first one I notice to be rude on MacRumors for not even fanboyism.
