This is more of a pipe dream, as I know the chances of this happening are unlikely.. However as someone who has played the game since 1.0, the current formula is getting a little tired.
This game is all well and good for newbies who are just starting to get into it now, however I am sure there are many vets out there like me that enjoy the game for the most part - but are getting a little burnt out. This weekly tome / weekly raid lockout formula is getting a little tired, and I really feel as though it needs to be mixed up a little bit. The formula was fine in ARR, however I expected HW to change it somewhat which it didn't, and now coming into SB I can see that they are sticking by it. I can understand why, I mean why fix something that is working, right? But there are only so many weeks of capping tomes and doing 1 raid clear for the week that people can handle.
For such a loyal fanbase (being a Final Fantasy title), you would think that the formula would be designed more on the long term and evolve, rather then the current rewash with a different skin.
I was a raider throughout ARR, and raided a decent amount in HW, however have dropped down to very casual play during SB and I am just clearing the easier raids in SB through PF. I have been enjoying the game very casually by running raids in PF, and doing the casual stuff in the game, but I can imagine myself not sticking around for too many more raid cycles unless stuff starts to change, which is sad because I have enjoyed my time, and would love to continue if I wasn't just getting bored of it all.
I am hoping Eureaka breaths a bit more life into the game (however I am not really holding my breath). I am also hoping it's more along the lines of Abyssea in XI. While I hate going back and highlighting that tired old game, there were some designs in there that could really work well for a modern MMO.
My thought process of how Abyssea-like content would work in this game for people that are unaware of what it's like -
It would be an open world zone with no lockout (could be instanced like Diadem). Your party kills monsters to get a pop item for a mini-boss (something of moderate difficulty). That boss drops [xxx] that you trade in for oils/coats/dips to upgrade your tome gear (or relic armor if that ever comes). It also drops 1 of 3 items that allows you to pop a mega-boss that is reasonably difficult (perhaps on an primal extreme level of difficulty). This boss drops alternate gear (horizontal progression), and also drops an item required to upgrade your relic weapon...
I honestly think an Abyssea-like system would be fantastic in this game, alongside the standard raid cycle. In fact I would very quickly give up the 24-man raids for this kind of repeatable content.
Now I am setting my expectation of Eureaka pretty low. I mean we got pretty hyped about the new/overhauled version of Diadem, to find out it was just changed to a zone full of Fates and a raid-like boss that pops once in a blue moon. Let's face it, Diadem was a pretty epic disaster and got boring extremely quick. I am hoping Eureaka will be a totally different story.
The most important thing for Eureaka to have is NO LOCKOUT or daily/weekly cap. Content has to be repeatable. Something that you can just band your friends / FC together and just go in whenever you want, with any number of people - and get stuff done. I understand SE's need to gate progression behind these lockouts, however they are possibly the most community damaging system they could use.
