Geez this is early to nerf things, especially given how downright easy everything already is to achieve... was a month too long for a casual player to approach endgame or something? So is this going to be one of those games where they have 2-3 things to do at cap, then they add ~1-2 more, nerf the old ones into obsolescence, and just keep on like that for as long as one can stand to scale the end-game ladder?
I was hoping there would be long-standing events, creative builds, and side-grades, but it looks like XIV is going to be using the whole "get the best gear so that in three months you can throw it away for the new best gear" ad infinitum. Can't say I'm very excited about that...
I believe your definition of easy, and the rest of the worlds is DRAMATICALLY different.
While nothing in this game is impossible, but, just going through the list of things that can (and do on a regular basis) suffer from repeated failure:
AK (yes, people die against the wall, and the biggest failure ).
As for nerfing, they already said when they were preparing for the launch that with each expansion, they would make it easier for people to make it through the older material.
Considering, even today (only one month after the launch) I have problems finding people who are even willing to run CM to help people get through for the first time, I can't even imagine what it will be like to get through any of the above mentioned things that do result in quite a few wipes as you learn the mechanics.
So, while I too do not agree with them doing it, it doesn't change the fact that the community really forces their hands in the matter. The idea is to get as many people to play on a level with other people. This of course (as has been said in this thread already) is met with people then feeling more of a rush to outdistance themselves from those who can catch up.
Rinse and repeat.
And that I would say is the new conflict for the developers. They want everyone to have a chance, but the community wants to be the best. As a result, you will have people who feel that others are getting a hand out by not needing to beg people "Better than them" to help.
