This has been a huge debate in season 1 and I still feel the same in season 2. Relying solely on challenges isnt the way to go.
Games like fortnite, cod, and destiny have other means of ranking up that are way more effective and alot less stressful, especially when we gotta sit through game after game waiting for the right playlist or mode to show up. Waste of time, waste of money on challenege swaps that shouldnt even be a thing IMO. But 343 just cares about the $.
Why do you guys think the player base is so much lower than many other games right now?
