So a DLC is 17,50.
You get, and this is bottom of the barrel in terms of playtime, it will probably be longer:
4 * 20 minutes (Story)
2 * 30 minutes (Strikes)
1 * 6 hours (at least first time - Raid)
Thats:
8+ hours of content in the DLC.
+ 3 new Crucible Maps.
Why is everyone turning braindead when it comes to Destiny? The DLC is pretty good value compared with every other DLC that is out there.
And with the release schedule it is ~8bucks/month. Totally normal for a MMO and you don't have to buy every DLC.
The game in a nutshell:
Go here, press square.
Fight waves of enemies.
Go here, press square.
Fight waves of enemies.
Go here, press square.
Fight a boss who is more or less a stationary turret since there's never any room for actual, honest to goodness mechanics. During said turret/bullet sponge fight, waves of enemies will spawn as a "fight mechanic" to aid in ammo replenishment since the boss is a bullet sponge since there is no engaging boss mechanic in the current game that feels like gameplay.
8+ more hours, huh? Huh.
You know, maybe if there was some compelling gameplay coupled with a story that was just as compelling... Maybe if every enemy did not use the same AI routines (OK, fine, some run at you, to be fair) and maybe if every box fight wasn't: sponge, weak spot, enemies, sponge, weak spot, enemies... Maybe, just maybe we can get more excited.
Just my .02. Nobody is "braindead", as you suggest, some people just want diversity of content and not the same drivel mission after mission. The structure is god awful in Destiny. Piss fucking poor and its a damn shame.
