This axe, available at level 56, is a worthwhile investment.
Currently 30-35k on Kujata its DMG 43, delay 281, and DPS 9.18 is 0.01 DPS higher than Fransisca which is not available until level 63 and farmed off a NM on a several hour spawn.
Fransisca is very slightly better to Weapon Skill and TP with because the base DMG is 1 point higher and Fransisca has a 0.2% higher TP gain/hit.
There is no reason not to upgrade to Fransisca at level 63, but for you aspiring BSTs, an Axe that you can get 7 levels before Fransisca with basically the same stats is worth grabbing.
