They have a financial incentive to adjust drop rates to make it appealing to buy the boost, making it a worse experience for anyone avoiding buying microtransactions. This is the path in every game with these microtransactions, and it will happen with Destiny, but every single time there are people lacking critical thinking who scream why does it matter.
I gave Destiny a new try with the expansion, after all the praise it got, then immediately dropped it once microtransactions were announced. Once that starts obviously it will lead here.
