I still want to see a debuff that effectively levels down the target, and with that all stats and possibly removing a trait or spell from their arsenal if the level is thusly moved below. And since having multiple RDMs in an alliance for debuffing purposes is often pointless, I'd like this spell to take a page from DNC steps and have levels where multiple casts add to the effect, most likely 1 level per successful land with a cap of 5. Recast could probably be around 45s.

Actually, I'd like the potency building mechanic added to all of our debuffs, job exclusive sort of like how people /SCH can't get Regen boosts with Light Arts. Saboteur could also be tweaked to land whatever at its max level along with the current boosts.

But really, pick a stat, and you can probably make a debuff for it if there isn't one already. Some would be more useful than others, sure, but having options for those niche scenarios would be nice.
