I have no idea what your talking about, i've been playing this game for the exact same amount of time and nothing has changed. The game still massively caters towards newer players and those who spend a lot. In fact the birthday pack was a really nice opportunity to give players a little bump in competitiveness amongst eachother without it being a threat to big spenders. Will cloak sakura help a 60k beat a 105k? not even at 10 stars but it sure as hell helps when fighting someone with 65k power. This wasn't a huge change for the whales they already were going to beat the average f2p player. this was about f2p players having the chance to finally get some reasonably priced useful ninjas if they have saved up a bit.
