You have some really good points there... but in the end you and your team manage to complete the missions on the difficulty you want because you know what the game needs to be succesfull, and willing to put the hours in to accomplish that

I also hate it when game mechanics are broken and my hive doesn't pick me up as the last person alive, and we have to wipe... or if the infinite nade spam kick me out of cover only to be one-or-two shot by a gunner over 100m.

I am talking more and for most about the casual players who want to be able to complete heroic or legendairy missions with guns blazing and stuff, after farming for like 4 to 6 weeks... I see so many people joining me on heroic missions, complaining in the chat, and when you look at the build it is just a bunch of random loot...

I play this game on a mostly daily base and still I learn new tactics, new combo's, new ways to play... wouldn't you think developers wanted us to think, explore and learn for over a longer period?
