These items are way, way, waaaay too overpowered in Tier 3.
Vog Cub: This set has a total of Very High attack speed, which is an insane defensive and offensive advantage for swordsmen. It also set has resistance to the most common status effect (fire), and defense against the most dangerous damage type outside of fiend strata (elemental). It doesn't have A SINGLE status penalty, while some other offensive sets like Mad Bomber and Chaos have penalties against several statuses. It needs be given a vulnerability to freezing, and attack speed needs to be lowered from Medium to Low on each item.
Owlite: Elemental attacks hit the hardest, so having elemental resistance makes this one of the most useful general-purpose shields. On top of that, it has defense against two common and dangerous status effects. Normal defense needs to be lowered or replaced with shadow defense, to make it merely a useful shield instead of a shield that's better than almost every other shield.
You're comparing Mad bomber, a purely offensive set, to the rounded Vog set. Try Volcanic Demo.
