I said long ago I expect rdm dps and sam tank.
I dunno why we need more DPS.
Not really need but when you break it down a 4th melee would make sense. A standard party is 2 tanks, 2 healers, 2 melee, 1 ranged/support and 1 caster, it can be varied if you want but that is what they design 8 man content around. In the dps realm of that we have 2 jobs competing for 1 ranged and 1 caster slot each, but then 3 melee split between 2 slots, of those 3 melee 2 of them bring perks that affect other peoples ability to do damage (disembowel, trick attack etc) while monk instead brings things that improve survivability (dragon kick and mantra). So on paper at least having a second melee in the same vein as monk would fit the bill, perhaps getting a str debuff shared with pld in the same way monks dragon kick can be subbed for delirium.
Also unrelated but this was a grumpy looking cookie
