Reaper needs additional buffs.

Even with the buff it got it's still going to be worse than the other melees by quite a significant margin.
Pls make the job not bad <3.

RPR's fine like that, he's not a pure Dps.
With a well placed shield, you can heal your team via a HoT. You can buff your team +3% Dps and put a debuff increasing 10% dmg on the target or in AoE.

It's a kind of NIN.

It doesn't dps as much as a SAM or something, but it's pretty decent with the right stats.
