Second, you make an assumption that any time spent could/would be better spent elsewhere.
The fact is that Turbine's development team can't release an update without breaking the game and any development time spent doing anything other than fixing a broken product is a waste of time.
Only that isn't even fact, since development time is valued based on sales. So Turbine doesn't care about your assumptions or about breaking the game every time they release a new update. All they care about is $$$.
And, as long as that keeps coming in no request for development of any type means anything to any of them.
