I've been lurking on these forums, for a very long time, but this thread has brought out the most face palm ever, this guy here, he gets it.
If there was a "loot lockout" I would force my FC to level a second character, gear them out, then run 7 alts and 1 main for coil, and do this 8x a week, and be geared for every class for everyone on their main in just a few weeks (depending on drops). this would instantly break the game, not to mention the fact that it would require a ridiculous amount of time, but, that doesn't matter when progress is at stake. for a top end FC, they would do this, guaranteed.
the lockout is simply a way of saving players from themselves, and not forcing them to burn out on the content. if you had to do coil 9+ times a week, and all but one of those times, you got nothing, how fast would the burn out be for you? for someone else, maybe not so bad, but for me, and for other friends of mine, as well as many people when this same idea was proposed in other games, said this kind of thing would kill the game for them.
also, difficult content that is made for DF is being made right now, its called Crystal Tower. wait another month until it comes out, then you have your tough DF content. They plan on doing it this way, top end small static group patch (like coil) then casual friendly raid patch DF unlocked (Crystal Tower, stuff to be determined later). this will give content for those groups of players. You can still pug coil, in a shout group.
This is a social game, dungeon finder will not increase the social aspect of the game, in fact, it does the opposite, keeping coil the way it is, is GOOD for the game. You might not see it, But I do, because turning coil into a DF wipefest will not increase peoples enjoyment of the game, in fact, it will lessen it, because the social aspect will get thrown out the window and everyone will go at each others throats in those groups until people quit the game. There is very many more cons to this idea then pros.
This would also make people sell coil runs, people pay good money to get run through titan, full coil gear in a couple weeks for a couple million gil? sounds like a good deal. if you don't like people selling titan runs, get ready for the people selling coil runs, and it will be much, MUCH, more rampant.
These ideas from similar games have been debunked numerous times, for these reasons.
