Just about everyone in this thread is completely misunderstanding the OP.
He's talking about a potential class ability like this:
Code:
Monk:
Foggy Brew
60 sec cooldown
30 energy (5% mana)
40 yard range
The monk douses the target in a Foggy Brew, lowering the target's maximum range on
all abilities to 10 yards for 6 seconds. Abilities with a range of less than 10 yards are
not affected.
This would have mostly PVP applications, a form of long cooldown CC where the target is forced to use heals/ranged attacks up close for the duration. It could also be used as an effective temporary silence that doesn't completely lock someone out. It could also be used in PVE as a caster mob dragging spell.
Another variation could be:
Code:
Warrior:
Off-Balance
(passive)
The force of the warrior's special attacks cause the target to be off-balance for
5 seconds, while your target is off-balance, their maximum range on all abilities is
reduced to 30 yards. Abilities with a range of less than 30 yards are not affected.
This would mostly have PVP applications and simply force ranged casters to sit within 30 yards to attack the warrior assuming that they've taken a melee special from the warrior within the last 5 seconds.
