The SWTOR devs used to be against dungeon finder tools, however they caved and are going to add them. You can read about it here. http://massively.joystiq.com/2012/03...r-the-future/4
Rift devs used to be against addons. But they added them.
Rift devs also used to be against cross server lfg tools. But they added them.
SWTOR devs were against combat logs. But they started adding them.
What do all these have in common? Players want these tools. While the vocal minority purists may be against them, many players do want such tools. Trust me when I say that within 1 year this game will have addons and full combat logs instead of just personal logs.
Notice I said purists, not casuals. Casuals are people that enjoy experiencing the content instead of having a challenge. Casuals are the ones that play for a few hours a week. Casuals don't care if you put addons in the game, combat logs, or dungeon finder tools (although with their limited time they probably prefer dungeon finders). Purists however are the ones against addons, combat logs, dungeon finder tools, etc. Purists try to call themselves casual, however they don't realize that purist doesn't mean casual. Purists can be hardcore players that dedicate a lot of time to the game and want to experience the hardest content but make sure it's with nothing but the UI the devs give them. Casuals on the other hand cannot by definition, be a hardcore player.
