Well my idea was keeping the cap the same but changing the scaling of the modifier for dmg enmity from lvl to hp... though a scaling cap might work but it might still run into the problem of as dps rises tanks that rely on fixed hate jas/spells would fall behind to dds so it might require small adjustments as time goes by if they raise especially if they ever increase ilvl. Changing the amount gained based on hate should be effectively a permanent solution... well at least until SE starts putting mobs that heal themselves too much
