Answering some questions

[Radacci]

I'm curious as to how much different the jobs at Lv. 50 will be in ARR compared to 1.23. Could you show us some footage of each job and describe in detail what moves and traits have been changed, added, removed, etc.?

This will be shown in class videos, before phase 3 start.

Are there any plans to include any types of party-based Disciple of the Hand/Land-only content other than Hamlet Defense? I think it would be cool to have friends help you in building large things like housing, airships, etc.

You buy land, and DoH craft houses, furnishing, etc.

I'm not a huge fan of one-on-one PVP, but in Guild Wars 2, there is a large-scale PVP area called World Vs. World, where hundreds of players from 3 different servers siege each other's castles and compete over territory, and then earn benefits for their server based on their progress. I enjoyed playing this, and was wondering if there are any plans to include some type of similar content where members of different linkshells, free companies, grand companies, servers, etc. could compete with each other and earn unique rewards? I would love to see players in airships and magitek armors battling each other! Also, would there be any technical limitations (culling, lag, playing on PS3, etc.) in regards to implementing something like this?

There's frontline PvP, which they haven't talked about much, but supposedly it's larger scale pvp than coliseum.
Coliseum is 4v4.

A lot of players are still in the middle of their relic weapon quests from 1.23, and it was previously stated that we will be able to pick up our progress where we left off. However, it's pretty apparent that most of the geographical locations and game mechanics associated with the relic quest have been changed dramatically since then, and I know a lot of people would be very upset if they had to redo certain parts of their quests all over again because of these changes. Can you provide us with any details as to how different the relic quest steps will be in ARR?

you wont have to redo anything. all progress has been saved.
they talked about it last live letter, and all they said was the above, and it's will be easier to follow what you need to do.
i don't think they will say much more than that.

Can you give us details regarding what changes will be made to materia, and how existing materia and multi-melded equipment carried over from 1.23 characters will be adjusted? Will materia actually provide us with new abilities instead of just stat-stacking?

hmm they said that items will have slots, that you fill with materia. higher tier items have more slots. you can put in more materias than you got slots, and that's multi-melding. items have stat caps, depending on tier, so you shouldn't go all out of STR materias, for DRG or whatever melee. would be nice with pvp materias, with some abilites or such, other than that...think it's just stat-stacking for now.
also you can put any materia in any gear; so it's not limited to str in only weps, and gloves, or such.

When can we expect to see some new details regarding the overall storyline of the game (what happened after Bahamut seemingly Megaflare'd everything, what happened to Louisoux, the Garlean Empire's plans, Ishgard's role in all of this, status of the Grand Companies and their leaders, the Echo, etc.)? Will we see some new things in Phase 3 and/or the upcoming E3 event regarding this?

Phase 3 will have a bit more of campaign story, but they will keep most unavailable for beta, as not to cause spoilers.
There won't be any echo related quests at launch, but later.

Will the ability to dye clothing extend to Grand Company gear and chocobo barding?

yes, they mentioned in last live letter, that you can dye barding. i think only AF will be un-dyable; at least to begin with.

Aion has alot of hair options, like 30+ for each race. Could we expect there to be as many in phase3?

From blog post, it seems there will be close to 30, if not more hair styles to choose from; and they will add more by launch.

Can we expect the npc head above text displays to change during our gameplay? Have those options be added on to depending on where we are in the storyline/quest line.

i'm not sure what you mean, but different types of quests, have different icons, so you can easily see what quests they provide.

Alchemist we all felt in XI & XIV to be role which wasn't very profitable comparing to other crafting jobs.

Can we expect Alchemist to add add-On Stats to crafting armor and weapons.

+2 Fire Resist, Def+3, etc.

that's what materias are for.
but would be interesting to see what changes are made to alchemists.

Is there a chance this game will a free-to-play MMORPG just like the rest of Pay-to-play MMORPG these days?
I prefer this game as pay-to-play MMORPG though

games usually go f2p, cause the company needs money, to pay back sponsors.
XIV is funded by SE itself, so they won't need to go f2p.
XI did well for 10years already, and is still p2p. ARR will probably be even more successful.
