Feeling cheated about what? If you're not having fun don't play. These nerfs are to allow people to get to T12 content with T11 gear easier. If you're so butthurt about your investment you really need to sit down and have an honest discussion with yourself about what is fun for you, as it is not the same for anyone else. T11 content being easier allows more people to get the gear for T12 content and I welcome that. I enjoy people getting to see bosses that would have taken weeks or even months longer to reach. Also, coming later into the game without "Freebie" heroic gear and easier earlier tiers makes the entry level for getting into the higher content harder, they're just lowering the bar so more can enjoy.
