That is exactly how it works.... being only 10 ilv over vs 90 ilv over it a big increase in dps it makes the dungeons or fights easier.
I did one of the omega fights recently and the other PLD tank had 50% more HP than me 75k vs 52k, does he need that to win the fight? no.... Do the DPS need the extra dmg to win the fight also no... the fight wasn't designed that way but there is no ilv cap to make it as it was intended. You literally skip mechanics/phrases because your group are doing too much dmg not hard to understand how ilv works.
