Item Level - How high will it go?

[CaptainLagbeard]

If we assume two things, one that it will work like it did going from A Realm Reborn to HW, and that 270 (for armor, 275 for finished Anima Weapon) is the highest ilvl of HW...

130/135 was the highest for ARR, 115 was the lowest in HW, this would mean Stormblood gear starts at 245, rising 5 ilvls per level and reaching 270 at 64 (275 at 65 for Anima Weapon) and Maxing out at ilvl 300 from the first Level 70 dungeons.
First tomestone gears (ones bought with Allagan Tomestone of Law) were 10 ilvls higher than the gear from the first dungeons loot (Neverreap and Fractal Continuum) so Stormblood's would be ilvl 310.

If we assume 3 new sets of Tomestones, ones that worked like HW, their Ilvls would be 340(350 upgraded), 370(380 upgraded) and 400(410 upgraded).

We have four digits of ilvl in our character info.
So maybe 9999? One day...

Asuming they will use the same system as now.

For stormblood:

First gear set will have around 255 (higher than Lore but less than Scripture), just as 115 on first HW set (higer than soldiery, less than Poetics).
Poetics was useful till level 55-56, so, probably 270 Scripture gear wil lbe useful till 65-66.
Last Stormblood leveling dungeon will have around item level 285
First crafted gear will have 290, 20 more than Scriture gear (first HW crafted gear was 150, 20 more than poetics).
First end game dungeons will drop item level 300 maybe.
First Tomestones gear will be around 310-320
Now, HW tomes and raid gear jump between tiers are +30.
Second tier gear will be around 340-350 (355 weapon), 330 Omega normal
Third tier gear will be 380-390 (395 weapon), 370 Omega normal
Fourth and last tier wil lbe 420-430 (435 weapon), 410 Omega normal

But. I'm sure, probably, the level jump wil lbe even more than +30 per tier. This is just asuming the same progress as HW gear.

I think the op should be asking the question "how much more of of a crutch will ilvl be in 4.0?". We've already seen it in ZEX where people expect to skip soar phases. I'm sorry but unless everyone in the party has 270 weapon at minimum and not including the other gear they won't be pushing anything but their luck. SE really needs to ease up on the ilvl as it really has made it apparent to me that a majority of the player base use it as a gauge of player skill. Which is wrong and will continue to degrade the party finder. I'm 3 weeks into 3.5 and I still can't find a party that can handle soar without a death and I made it to 19% on the first day with TWO tanks.

wow hadn't though about it but i has only been 140 ilvls =D not too shabby for a 10 lvl gap, in wow think you see 140 ilvls from one raid to the next lol. The ilvl creep in wow is so damn monstrous lol.
