How powerful would the spell/ability 'Stop' be in this game?

[JunseiKei]

Technically, Alexander uses Stop. If a player had it, it would probably be like stun (a timer with stacking resistance with each use). It might have niche uses, like slow did in some fights, but largely unused.

(Shadowbind used in T7, but many groups uses SMN's Miasma for the slow to effectively stop Renauds in place without removing their default Heavy debuff.)
(Silences used in T1, T2, T9, A6, HM-HM, Mhach, Mirka hunt, etc.)
(Heavy used in T5, T7 and I swear there was another time in Alexander.)
(Stun used in T5 and single add in Leviathan EX.)
(One Ilm Punch used in T4.)
(Pacification works on mobs who can be silenced or stunned out of their skills.)
(Sleep is useful in low level dungeons and Palace of the Dead.)

Unfortunately, SE said they don't want to make fights where you need a specific role to do something, so don't expect those skills to get much other uses. Likewise with Stop, unless it basically does the same thing as something else (bind, stun, etc.), it wouldn't really get actual use. Much how SE is reluctant to give players Haste (let's be real, arrow cards are basically Haste and most TP DPS hate it), I doubt we will see Stop as a normal debuff players would obtain.

Petrify and stoning exists in T7 and Mahees hunts. Before nerfs, tanking any damage while stoned in T7 caused instant knock out. Petrifaction (the skill that caused it originally) may stone, but it only gives stacking invulnerability now, like in Void Ark.

exactly. why bother having them if they don't intend making use of them.... it's why a lot of the "redundant" skills se is looking at removing / changing are the skills that have these effects. redundant because the effects are never useful.

Or they will place more mechanics that will need them since you have access to those skills spread throughout more classes than you did in 2.0. My point was more to if you need one particular skill to do something, then we probably won't see it. Like One Ilm Punch's current effect of stripping one buff from a target. You know, since it's the only skill with that affect.

However, thinking on what Stop does- it effectively makes the target take more damage from multiple opponents before it is freed. It could effectively be made to be just like Trick Attack. Remember, Storm's Eye and Dancing Edge do the same thing. Dragon Kick and Delirium almost do the same thing. Just something to think about; Trick Attack and its effect are kind of ninja's ticket into raids with the current skills at its disposal, so I don't see them changing that so soon without giving them something else.

Again, unlikely, but just food for thought.
