I just had a chat about RF with a friend. We talked about many of the issues regarding Raid Finder.
Some of which is that it occupies alot of players because of huge rewards for little(no) effort. This often make filling a group to several instances just about impossible.
As an extra disadvantage with this new players that are yet not good enough to do the more challenging instances like the ones in dragon spine.(Which are the only ones that are done regulary) New players should be able to learn in easier dungeon and Khitai is an exelent training ground. But it does not reward anything noteworth so the few players who know them only run the harder, more rewarding.
Also when new player who are done grinding RF and got full t4 they now are going from a no-brain walk in the park facing really challenging content if they want to progress any further. This leaves a HUGE gap in the learning curve.
If Raid finder were only available for one week a month, like World bosses or PvP Festival. There would be 3 weeks where people do actual content. This would give new players faster gearing up to T4 while at the same time giving them 3 weeks every month where they could access easier content like thoes found in khitai. So that when the time t o proceed from RF came they could actually handle the content.
For everyone else who want to enjoy all the extremely good content of the game, the benefit of this would be undeniable.
