Frontline and i80 twinking gear sets

[Pequenisimo]

So, I'm wondering about Weapon scaling. the DPS of weapons does not scale the same as the Stats of the weapons. Here is an example:
Titan HM weapon i80
DPS = 14.67
27 str, 30 vit, 33 parry

High Allagan Axe i115
DPS = 17.67
45 str, 53 vit, 46 parry

If you scale i115 to i80 at that ratio the High Allagan would become:
DPS = 12.29
31 str, 36 vit, 32 parry

So..... does it scale directly to ilvl giving High Allagan much lower DPS and higher stats?
or is it scaled to DPS giving High Allagan equal DPS and much higher stats?

Either way, the DPS and the Stats do not scale equally with ilvl and makes it hard to choose the BIS weapon.
