@humanity: I don't really agree with that - especially with Damage 2.0 just having been pushed out the door, which was a massive issue previously (the fact that only a handful of weapons were worth using, I would argue, was one of, if not the biggest issues the game had) - weapons are still not entirely balanced (see Brakk, Boar Prime), but it's a lot better than it used to be where only weapons with armor ignoring damage types were worth using.
There's also the whole PS4 version, and pushing out Update 11 for the PS4, cross platform gameplay.
Seems to me that, while it's a significant oversight (that should be adressed), it's not that big a deal that you can't place waypoints.
I see what you are saying with "concentrating on the front-end" - my counter argument is that they understand that they need to maintain a balance between new content (bi-weekly Tenno reinforcements, major updates every 2 months or so) and fixing things (Damage 2.0 and everything else that was fixed in Update 11).
*shrug* My opinion, anyway.
