The last patch hurt a lot of people. And yes people are already giving up, so things need to reversed and fixed so there is still some hope.
1. Saritova spawns - The golem spawns all over the island have been slashed heavily.
-The fire opal spawn was abusive and should be changed to a linked field similar to the rest of the golems, more remotely linked than falling on top of eachother. The other area for fire opals to spawn has more of every other enemy in it than fire opals.
-The old spawn had good numbers of golems in two or three linked fields spanning over 1000m or more. There was also prehaps 5 different golem spawns, so if you killed all of one, there was always another type of enemy close, or you could make a decent run to the other field and get them there.
-Currently there are very few golems, you can kill the few that are around your area and just spend most of the time running and looking for more. This posses big problems with just normal people looking for tech components or trophies, or plain experience. Not exploiting anything, just playing. Groups are pointless in this area, there is not enough to kill. There needs to be a large increase in the spawn.
As someone has pointed out, this has lead to a lot of nodes being unguarded right near large communities as well.
2. The Mithril's Anvil spawns much like the Saritova Island spawns have been hacked and slashed. It was a very nicely balanced field before, with no massive groupings (unless you pushed all the golems purposefully to one area) or major barren areas. Current there are only a handful of golems that exist. Combined with Saritova's reduction this makes mithril frags extremely hard to obtain, and used in a huge variety of techs.
3. Satyr island tech comps. With Nadia's price increase and the general rarity of mobs was gonna be a sore point. With the newly added agro code means that hunting these islands is just sucidial, its no fun for anyone. I can recongization a challenge, but its like you are a magnet no matter where you try and go and fight. I know the agro code is pretty much just being tested right now, but keep in mind that these comps are mostly unattainable.
4. Tier 6 nodes. While I am in favour of t6 being difficult and unique, there seems to be a line that was crossed for many. Why should tier 6 exist if transmutating t5 is faster and takes less skill, less camping, less danger and way less highly teched out gear? Please relook at this area, it just makes very little sense right now.
You could add anchors to the areas to make them dangerous, add more mobs generally to increase the danger, but just cutting the numbers down so severely seems wrong. Give them a boost in the least. I don't care about t6 myself.
5. Old Oaks. Over the last few months the Old Oaks area has taken a beating. And the Anchors just south of Old Oaks are cutting people off from a linked silk field, as well as shining wisps. While the yelling isn't as loud here, its still a concern. The silk there gets you killed, and the linked last stand field gets quickly used. The shining wisps with the new agro are very very hard to get to and well guarded. The swamp has been infested with Kwellens which will kill a crafter in one hit, and the only other option is the yew forest. The yew forest's spawn of shining is so small one person depletes it, if a person kills the wisps (and a lot of people do) running into the treeant spawn is more sucicide.
I completely understand why most people are mad, why they are quiting. Right now things just are not attainable, and unless things get changed they never will be. Nobody is looking for their "I win" button, but people have invested their time here, to see it ripped out from under them.
The design of construction, and hunting in Istaria is based off of big numbers. We need to do things a lot before we finish or achieve anything, and when those numbers are ripped away from us, how can we achieve anything? How can we continue to play a game where we can't achieve?
If there are any other issues I've missed, please post more. I'm not calling for a complete reversal as I agree on many things the devs have done and some of their direction, just a lot was taken too far.
