I somewhat agree with you on the weapon. There's not a good way to get one of those.
Eureka Weapons(Low skill, Supposedly "Play to Win", but also takes less time than building a fresh learning static from O9S)
Tomestone weapons also require Normal Raid drops. (Low-medium skill, Guaranteed within 4 clears and 1k tomestones)
Extreme Primals (Medium skill, Guaranteed within 10 clears)
Savage Raid Weapons (Medium-high skill, luck)
Ultimate Trials (High skill, Guaranteed within 10 clears)
Oh, and Crafted. (No skill. Gib moneys)
Highest casual weapon is 300, and the weapon does impact your damage probably the most significantly. This is one of the more surprising changes from Heavensward to Stormblood that they have made, removing weapons from the level cap dungeons.
