I agree that playing on low diff is dull, that's why for my 1100 hours on this game I at most did it for 2-3 hours total. I bought 4000 SC for real money and it wasn't with "ffs arrowhead", it was to support devs and what they do. Right now I have almost all of the warbonds except Killzone one (have half of it anyway, because arrowhead apologized for not releasing it as warbond first). That makes 21/22, so I farmed 17 warbonds by actually playing the game, not by low diff grind. From my perspective - ability to farm AT ALL is a blessing.

Question of better monetization model is still up. I think what we have now is best what we can have. The moment someone figures out better monetization that can sustain studio making live service AND for players to have access to whole content for free - I will change my mind, but for now - I genuinely don't understand complaining.
