Yeah in theory that's nice, until every encounter breaks because stuff. See AoC raiding, wasn't tested, everything was massively exploitable and mostly a bunch of shit.
I agree with that, but there is another side to that coin as well.
How do people usually figure out raids? By doing them repeatedly until they figure out the mechanics, at which point the raid goes from difficult to steamroll fairly fast. Coil in FF 14 being the example, people doing turn 5 was it? Over and over and over. Then someone figured out how to do the tornado thing (I've never done it, only seen videos) and the coil went from "world first" to being done regularly on every server within a few days according to the thread. Reason for that was not that the various servers suddenly geared up to the required levels, but rather that they figured out the mechanics by reading up on what someone else did.
Say the beta squashes every single bug and exploit due to massive amounts of beta testers actually doing their job, and testing and bug reporting every single raid. Come release, what will happen? Every single raid will be known beforehand, and only the most basic of pug raids will not look up how to defeat those raids beforehand. Once the NDA drops, the details of every raid tested will be available, and the path of least resistance
willbe taken. No raiding guild is going to have a moral "oh no, we have to figure out this for ourselves, no spoilers". Especially raid guilds who are interested in world firsts and the likes.
So what will happen then? Content will be blasted through because the end game will already have manuals for it on how to beat it.
I think the best thing would be to handle it internally, but it would require lots of internal Q&A testers, which would cost a lot, money better spent on developing the actual game, not testing what is already there. I have no idea what the best way to do it would be, but I see why Byr made the statement.
Also, why is it so hard to get 40 people to raid today when EQ, with a much smaller player base than the mmos of today regularly did 72? We waited, we traded accounts, everything to make it work. Then again, we had to talk to eachother, which seems to be something mmos really try to avoid these days. Community be damned, we should be able to solo everything and communicate with nothing but emotes!!!...... /sigh
