Wholeheartedly agree with others on the trade changes- please just don't go there.
On the fence about ancestral skills. If you look at them carefully and balance the numbers, I'm fine with it. It's always fun to get new skills to use, but some of them were incredibly overpowered and leeched life out of pvp by allowing no reasonable counterplay.
I didn't like the crafting changes. Leave the recipes as they are, generally. Other people have already explained my reasons for this (messes with the economy, basically). There are some small tweaks that could be okay, but this basically f*s over people who made their gold through crafting or selling crafting materials. The economy here is just about stable again after Goldbuyinggeddon, please don't turn it completely upside down again.
The new zones could be good purely for PVP and more content, I don't think they're necessary but some people like them so I don't see why not. An opportunity for more land would be nice, honestly, because this server is seeing an influx of new players and I often see them complaining that there is no land available for them.
Please don't f* up the timers any more than they already are. NO to the Halcy changes, NO to the set boss timers (aside from RD and Kraken), etc. This server has a LOT of EU and OCE players who already can't participate in almost half the ingame events. If anything, move the timers back to Central time to make it fairer for everyone! People should have fair access to things. It's not fair that someone can't ever do Morpheus because they work evenings or live in another country.
Many of the QoL and small changes were fantastic. The teleport book changes, the character screen changes, the rebirth changes, etc, all great.
The big rant:
Erenor gear... I'm against it.
It's all well and good to say "oh it's something new to work towards", but it just seemed massively unfair to me, even more so on this server than on live. Most of the people happy about this are people with already high GS, who have time and money to throw haphazardly at the game, while failing to consider other people or the health of the server. Even intelligent whales can see that this is bad for the server (and their pvp contest).
Erenor gear (and also the eternal grade) creates an even bigger disparity between players. Those who can swipe or completely no-life the game all day are at a huge advantage here and will have this kind of gear before many of the newer (or poorer) players can even hit a divine or epic t1. Someone with a mythic or an Ayanad can already 1-shot practically anyone else in the game, there is no need to give them even more power.
This was the start of f*ing over obsidian users in my opinion. Obsidian already comes with a set of disadvantages- it became harder to regrade than "crafted" gear, it was generally more expensive to get a T7 than an Ayanad, you needed it at a higher grade than crafted gear to make it worthwhile, it required a lot of boring PVE farming for bound materials and, perhaps most importantly, it is bound and untradeable. The payoff for this was that a T7 was almost always going to be slightly better than its crafted counterpart. Those who worked hard (or paid a lot of their irl money) to grind their way to a legendary or mythic T7 will have essentially wasted their time and money if their weapon can suddenly be outclassed by a tradeable celestial-divine Erenor, or by someone hitting a lucky proc to Eternal. It's not like they can resell their weapon and swap to an Erenor/Eternal one, because it is bound at its highest grade (and worth less than they paid for it). You're basically punishing someone for committing to their class/character enough to create a really expensive piece of bound gear.
