2nd that rdm has been neglected since 75. I would suggest completely redo'ing the t2 rdm merit category and giving scrolls with the spells. Aside from the idea, i think the devs should come up with what to put in their place.

Make enfeebles stick on more mobs. i feel like generally mobs are immune to at least a couple enfeebles. Add STOP as a spell (that sticks on HNM type mobs) 5~20 second duration. things from previous FFs come to mind now, MINI, FROG. doom would be bad for rdm since drk and blm don't have yet, same for death and zombie.

Make rdm's single target enhancing magic cast-able on any target. probably through a level 50 job trait or something so /rdm can't get the benefit. that should not overpower rdm's benefits. Include spikes spells and t1&2 en- spells with the trait as a small buff to counter the lack of anything rdm got comparatively.

Give rdm some holy magic natively. Should have never been removed in the first place.

Fix Blink: Make blink 100% activation rate, AoE only takes one shadow, and make blink's shaddow count be =Enhancing magic/100
@75 its still 2, @95 cap skill + gear its 4.
Reasoning: Utsusemi creates clones, IE multiple you's simultaneously getting hit by AoE. Blink makes you dissapear for a moment, IE you aren't there to get hit multiple times.
to balance it since /nin can use utsusemi: as well. double cast and recast timers.
