At its current state, The Division is good for a few things:
1. Story missions (I.e. Lvl 1-30 grind)
2. Completing the Map (side missions, Intel collectibles)
3. Daily Mission and Assignments (on hard mode and single player only).
4. Challenge mode missions and Incursions with friends only
Things that this game is definitely NOT good for:
1. PvP
2. Dark Zone on PC
3. Crafting and Loot Grind
Things in this game that are currently playable but may not be in the near future:
1. Dark Zone for consoles (if hackers infiltrate the consoles)
2. Matchmaking for Incursions and Challenge mode missions (if more and more players quit the game)
I don't know if the patches or updates will change things around or not. And the reason why I'm listing things like this is to reasssure players (especially new ones) that not everything is broken with this game (not yet). But the PC hackers, the glitches, and the endgame issues all make this game much less replayable than it really should be.
