I'm not a game designer, nor do I know what everyone wants to improve this game (or if they even think it needs improving) but these are just some idea's I had. There's probably flaws somewhere and I doubt it will ever be considered but I felt like doing this anyway.
Adjustments to Item Level
All new end game gear will be set at Item Level 250
All gear can be upgraded using Aetherial Core's
Number of Aetherial Core's required to upgrade.
Head 2
Body 3
Hands 2
Waist 1
Legs 3
Feet 2
Accessories 1
Aetherial Core's can be obtained via the following methods;
Weekly;
The Gift of the Archmagus Quest
Completion of Alexander - The Burden of the Son.
Completion of Alexander - The Burden of the Son (Savage)
Completion of Void Ark
And any other weekly stuff I forgot.
Other Methods;
Leve chests
Treasure Map chests
Diadem chests
Elite Marks
Beast Tribe Tokens
PVP
Guildhests
Any Dungeon/Trial/Raid Chest.
Maybe tomestones of Lore too?
Basically almost everything.
Aetherial Core's can also be traded and sold via the market board.
Upgrading Gear
You can upgrade gear by speaking to <npc> while holding the required amount of Aetherial Core's.
Each upgrade will increase the gear's item level by 10 and increase the stats accordingly.
The cap for item level will continue to increase as more patches are released, however all new end game gear will still be at Item level 250.
Unless that also increases every 6 months or a year so new gear isnt really far behind?
Changes to Gear
You can now find certain gear with bonus affects. such as Vit +5%, Fire resistance +5, Blind resistance +2 and so on.
e.g The Brand New Cuirass obtained from the novice hall has +5% Vitality. However its only ilvl 17 but you could increase it to ilvl 250 or higher if you put alot of Aetherial Core's into it. Coupling that with the other matching pieces that also give +5% Vit would be a good set for endgame tanking.
There could even be relic armor that starts at ilvl 1 and has a good bonus.
Changes to Tomes
The weekly cap for tomes will be increased to 900 and be job specific.
Adjustments to the combat system
Enemies will now have elemental damage and can deal status affects.
Adjustments to the materia system
All gear will now have materia slots.
The following materia can now be purchased from <Random NPC>
Cactuar Foot I
Coeurl Eye I
Aurelia Kiss I
Bison Hoof I
Funguar Shriek I
Treant Root I
Chocobo Down I
This materia now works with PvE, scaling at +1 = 10% reduction to duration. Therefore slotting 5 x Cactuar Foot I to your current gear would give you 100% reduction, making you immune to the effect of Slow.
This will not affect PvP
Changes to elemental Materia
Elemental Materia also has weakness including resistance.
Before
Fire Materia I
- Fire resistance + 1
Ice Materia I
- Ice Resistance +1
After
Fire Materia I
- Fire resistance + 1
- Water Weakness +1
Ice Materia I
- Ice Resistance +1
- Fire Weakness +1
This continues to follow the elemental chart.
Resistance & Weakness scaling:
Resistance + 10 = 10% elemental resistance
Resistance + 20 = 20% elemental resistance
etc.
Weakness + 10 = 10% elemental weakness
Weakness + 20 = 20% elemental weakness
etc.
