Personally I belive this will be a welcome change to the game. I currently have enough cards and power to play in silver 1 and am looking forward to being rewarded more for the amount that I curreently play, gradually moving to gold and beyond as soon as I can for more significant rewards.
I think the addition of 3000 credits for new accounts will be a good incentive for new players to get a feel for the game and whether they then want to start splashing cash and adding to the economy buy renting or buying more cards.
Whether you think this will increase bots or not, or you have an issue with bots taking value from the game to me is beside the point as this game is primarily about collecting cards and battling other players. The fact that you can earn real world benefits from playing is a bonus. The better you get and the higher you climb in the game the better these benefits become. sounds like a win to me.
