I'd like to see shadowflare as a targeted AoE with a DoT element vs what is is now. They should've had spells like:
Pearl: (holy/spirit damage) to replace Ruin, but keep blind effect.
Demi/Demi II: small burst damage with a DoT (replace Bio & Bio II)
Pain/Meltdown: Damage plus heavy effect w/ minor DoT (Make comparible to Miasma/Miasma II and replace)
Whirlwind: could act like shadowflare does now, but it would be something along the lines of the tornadoes the dragon spawns in SV NM.
With something like the above this would still make use of Contagion, Bane & Fester, but make SMN a bit more tolerable to play. It's my favorite class in the game, but atm it is very lackluster in comparison to BLM and needs to be different in comparison to SCH/ACN
Also I miss thunder
