Of course it's "weightless" - THERE IS NO BALANCE. Why? Because there's no PVP or endgame PVE content. You're all good game players. It doesn't matter how hard SE tries to make leveling, you'll grind your way past any difficulties. Level 40 mobs too hard? Grind more on the level 38 mobs, then you'll be OP when you fight the level 40 mobs. Leveling is always easy mode; the only thing SE can control is how long it takes.
When FFXI was out, it was new. You didn't know what you were doing in an MMO. That's always exciting. Everyone loves their first MMO, whether it be FFXIV, Aion (for me), or WoW.
Once you've played MMOs for a few months, solo leveling is easy. Group leveling is easy. Even instance leveling in WoW is faceroll.
If you want challenge when leveling, play on a PVP server. That's right, there's no PVP in FFXIV, because balancing PVP is really, really hard. And PVP is the reason Aion tanked in America (leveling in Aion was pretty challenging when rifting was still viable. It made it a lot more exciting and gave you a good reason to group up).
You need more than some wandering monster to justify advanced party tactics, extensive theorycrafting and complicated control schemes to use every key within reach to take down a mob. You need dungeons, instances, raids, PVP. And you need developers that fine tune that content to take advantage of every skill you have - AOE healing, single target healing, CC, mobility. FFXIV has NONE of that. It's got empty fields with lots of generic critters. Why? Cuz they didn't have the time or money to actually develop a game. And now that the game has released to abysmal reviews, and they're not making any new money on subscriptions, it's very unlikely they're gonna have 50 developers churn out dungeons, instances, raids, battlegrounds, whatever.
FFXIV is just lacking so hard when it comes to the content that every other MMO comes with, standard. You don't want raids, PVP, instances? Fine. Then put just as much work as Blizzard puts into that stuff into your ALTERNATIVES. Cuz as far as I can see, FFXIV, walking a different path, just left that stuff out - the hard stuff that every other MMO developer grapples with - without actually giving you an alternative. That's lazy as ****.
When World of Warcraft first came out in November of 2004, it had no end game content. It had a handful of zones all with similar "go kill 10 kobolds, come back and now kill 10 more, and now that you've done that, go kill some kobolds and collect their candles" type quests. There was pvp sure, but not in the newbie zones and there wasn't really any reason to pvp (no score, no points, no incentive of any kind). Pvp was just groups of people running around ganking you when you're low hp. Not challenging, not fun (yes I've played on a pvp server all 6 years of my off and on again WoW career). Pvp was NOT balanced or challenging. I played a druid, the only talent tree that was viable was restoration (healing), the other talent trees were broken. We had no offensive capabilities, all we could do was run around healing... and we didn't even do that well compared to other healing classes. We would barely even kill mobs in pve(other classes had similar problems, paladin for example). At least FFIV doesn't have any dead/ completely broken classes like that.
Blizzard was able to add a ton of content and balancing over the years because the game was successful. Even before the first expansion the game was completely different from the version at release.
I know this game lacks content, and lacks balance for combat, but I also think it is unfair to compare a brand new game to something that has not only been out for years but has been successful during that time. Games that get off to a rough start take longer to really shine.
