Honestly, what is this 'netdecking' you all speak of? I've always thought it to be a lame reproach.
If Blizzard prints 3 Warrior cards that have a 'bomb' in it's description is it weird that people play Bomb Warrior? Me and a zillion other players made a Bomb Warrior list before the expansion was out and honestly if I see the current decklists I dont see any card I hadnt included or thought of at the time. The same can be said of Token Druid because any player with some hearthstone braincells knew that a card that floods the board twice was gonna be great in a meta without Psychic Scream, Defile, Spreading Plague, Blood Razor, etc. & an expansion that hardly introduced any AoE.
I took a quick look at the current meta and I dont see anything original over there. The only thing I didnt think of personally was including a dragon package in Khadgar Mage. I also didnt expect Mech Pally to do so well but I could have generated a list nonetheless.
Most current meta decks were anticipated beforehand along with 20 others (just check Vicious Syndicate's preview). In the end the best ones of those 30 decks are now the meta. This opens spots for more unconvential decks that do well against this current meta and this is where the 'originality' will begin (and the netdecking will follow).
Hearthstone is a pvp game so you'd be a fool not to copy and try out things from your opponent's decks that you thought looked pretty nice. Wether it be the inclusion of a card in a deck type you were already playing or a whole new decktype.
What do you want? That all players lock in an amount of decks at the start of each expansion and are never able to change them because that would be netdecking?
Imagine a football coach complaining about the other team for using a 'Zidane dribble' or a 4-4-2 formation because they didnt come up with it themselves. That's how you sound to me when you complain about netdecking.
I hope you find back your fun but if you get annoyed by netdecking I would say this is not the right game for you.
