For point 2, my intent was to show that they could easily have prevented these cheese spots in the early development. Nexus cheese is intentional. Same with archon. The Valus strike and phogoth strike cheeses couldn't have been intentional. The development team is full of extremely smart individuals. They know how to make it work.
For point 3, the only excuse for us to not go to the enemy location is if the enemy is in a helicopter. At the end of the day, Destiny is only a video game. Finding a location that provides a tactical advantage isn't a cheese. It's called using logic.
Here's another point for you. Destiny is entirely directed at children. This can be seen in many areas.
1. Dry, boring, uncomplicated story. Easy for children to understand and feel accomplished with.
2. RNG. Because having a performance-based rewards system doesn't give the worst player their silly participation trophy.
3. No blood. No gore. Keeps the mind of a child somewhat pure.
Using this logic, and having proved destiny is geared towards children, why should it be overly difficult? That's the part I struggle to understand. It doesn't fall in line with those three points.
