Amazingly not everyone is rank 50 in multiple jobs, many have either RL responsibilities that limit their available playtime and quite a few people got bored with the game and left. Those screaming for "End Game" content (at level 50 as if it's the end all be all cap) I am assuming you think that content should be developed only for those at max rank and everyone else just needs to grind out and do things like intentionally fail leves for MAX SP gains.

It would be nice to have little quests or battle areas to collect gear along the way without having to hit max rank to basically "start" the real game.

Interesting idea to keep these dungeons relevant, I imagine they will be taking the rank to 75 at least. Similar to Salvage gear you could possibly collect special pieces that will be decent for their intended rank and maybe once you have the 30-50-75 pieces they could be combined into an ultimate piece of gear.

As for the quest hubs, didn't every single one of us ask for the zones to have more character, encampments, small villages perhaps some old ruins? This seems to be a step in that direction, for all we know it could very well operate similar to Campaign. The encampments could come under attack as well as they could send you out on Company related battle missions to assault a beastmen stronghold. In times of war you don't just have your base set up in town, you need to spread out to meet your enemy before they get that close.

I also see that they have gardens of a sort and crafting facilities so the DoH and DoL jobs can lend a hand to keeping battle operations running smoothly
