The current state of the game is this: People who did not have best gear before the patch (Kaia +15) are now denied all fun in endgame. The only thing they can do is grind three boring dungeons for a meager drop rate, which will not allow them to upgrade to +15 and unlock more dungeons anytime soon. This is NOT FUN AT ALL. People are gonna leave the game over this. I've seen many people being upset about this, both on this forum and elsewhere.
There are three possible ways to improve this situation:
1) lower the ilvl requirements for some of the 498 dungeons so that we can run more dungeons
2) add more dungeons for ilvls below 498 (event dungeons perhaps?)
3) make enchanting to kaia +15 easier so that we are not stuck in the three boring dungeons for so long
I will now elaborate on these three points.
First, the ilvl requirements seem unnecessarily high. I play a mystic with 490 ilvl (Kaia +11/+12) and I did two DANM runs after the patch (through lfg because I can't IM) and it was completely doable for me, had no problems running this dungeon. (Though I admit the ilvl might be more of an issue for a dps than a healer. But I still think lowering the requirements a little bit would not hurt the dps too much.) I have yet to test this in more hard dungeons (will keep this threat updated).
Adding more dungeons is pretty self-explanatory because more variety of dungeons = more fun. It would be great if they were a little challenging.
Another solution, would be to increase the drop rate of improved feedstock in dungeons or add another way to get this feedstock.
What you said in the patch notes about a "significantly reduced number of enchanting materials" was very misleading. Replacing EVERYTHING with improved feedstock (even repair materials and materials for enchanting below 10) does not make it easier to enchant at all. There is currently a shortage of improved dark shard feedstock (improved armor feedstock was completely sold out on broker the day of the patch). People were hoarding normal dark shard feedstock, only to find out they are useless in this patch. A solution to this would be add an easy way to get cohesion arcane to transform normal feedstock into improved feedstock. Somebody suggesed adding cohesion arcane in Elleon shop, which I think is a great idea. Or you could add it as a reward in some event. People who have hoarded normal feedstock would be very happy about this, and it would improve the situation around shortage of improved feedstock too. EDIT: It would be awesome if normal feedstock could be converted into improved feedstock just by righ-clicking, but I understand this would be technically difficult to implement.
EDIT: A great solution to the enchanting problem would be to completely remove the chance to drop a level when enchating Kaia, that would make it much easier to reach +15, needless to say that dropping a level is extremely frustrating. A similar effect could be achieved by implementing an easy way to obtain a 100% Serghetto's Safeguard.
Thank you for reading and possibly considering these solutions.
