Nobody will care much about tier 1 world firsts purely because there are so many variables that can benefit certain guilds that have a chance at it.
There are many ways to derive enjoyment from an MMO and progressive raiding is one of them, much like RP and PvP are others. It is no ones place to say what audience the game is made for because everybody would have been taken into consideration during development, so why flame people who are interested in world firsts?
It is dumb to say that nobody plays SWTOR for raiding because it is obviously untrue, if you're not interested in PvE progression then don't enter a thread about it. Simple.
