The current battle system mainly calculate everything from Your Rank vs Mob Rank

[Kurokikaze]

In my opinion, if a R50 Gladiator puts on the same gear as an R1 Gladiator, carries the same weapon, equips the same skill, and assigns his stat points the same (or leves them unassigned as the case may be) - they should do exactly the same damage, take the same damage, and evade the same.

If you think theres even an ounce of balance in that...
