I have issues with what the topic creators first points are.
Well ya if you piss on my head and call it rain I guess you could say that. I would say it's just a natural evolution to a game that is losing people faster than it's gaining people, while also raising the level cap.
75 is the halfway mark in exp to 90. 90 is the halfway mark in exp to 99 most likely. The increased exp in areas outside of Abyssea are to make it to where leveling outside of Abyssea feels productive for those that want to do it. Abyssea's massive exp is important because without a way to gain massive exp it'd take you 4x the exp it took to get from 1-75 to get to 99. How many people are going to keep playing the game if it takes THAT long to hit max. People were like "Well it takes about 6 months to a year for me to get a job fully leveled" well ya know what? Now it'd take you 2 years to 4 years to get a single job capped at the same exp rate you were already going at.
There'd be no possible way to keep FFXI going in large numbers with those kinds of exp gains. So what you're saying is just flat out a misinterpretation.
The other changes that have been made such as easier skill ups, cheaper Dynamis fees, and other things, are a response to the fact that as things evolve and change, there are other things to try and balance. The problem with Gilselling is everyone has the chance to get an unlimited amount of gil. If you just do Abyssea for a while and then use Cruor to exchange into items, and then sell those to the NPC for tons of gil. So they could have 13 afks, and 3 people for a Fell Cleave party, and if they don't stop doing the fell cleave party they could gain any number of Cruor they wanted then just stock up on items, NPC, stock up, NPC, Stock up, NPC and boom they have as much gil as they could desire on 16 different characters and that's way easier than going to dynamis for farming crap.
So I really just have to say that you don't have the slightest clue of what you're arguing about. Maybe I'm wrong, but if gil sellers were going to return, I feel like they would have done it at this point. Because quite frankly, making gil is easier than ever.
You can leech in a Fell Cleave party for 100k an hour and literally make all that gil you spent back in no time at all. Which is to say... before your time is up. And Fell Cleave isn't something they could really easily prevent. It's a product of having strong AoE attacks and a lot of good equips and Atma. They'd essentially have to create limits on how fast you can kill mobs in an alliance and get exp, which I don't think anyone would be asking for them to do.
So please tell me how your arguments are in any way shape or form valid. Plus I personally don't have any jobs to 90 that can use a relic. So... Dynamis means zilch to me at the moment until someone can tell me what dynamis offers me in some form.
