Mind Vision can be enormously powerful in Warsong Gulch, as the flag carrier can easily be targeted via /target <name> and then function as the target for the spell.
When defending a node Arathi Basin you can Mind Vision an incoming rogue or druid before they stealth, then pop them out with SWP once they come into range.
It can be used to annoy other people, as it cannot be dispelled.
As a consequence of this skill remaining 'glitched' (insta-cast spells work on your target while channeling Mind Vision) it is possible to chain-cast Mind Vision between multiple mobs/players. Useful for maintaining the watch on the flag in Warsong Gulch, or third-person scouting in raid encounters.
Combined with the Warlock's Eye of Kilrogg or the Hunter's Eyes of the Beast, this can prove useful for allowing multiple players to scout the same region.
Using /target to target a known PvP player nearby, then use mind vision to determine exactly where they are.
When trying to find a certain mob character for a quest, use /target to target them and then mind vision to locate them. When you leave mind vision a small dot appears on your mini-map for a second showing you where he/she is.
Mind Vision cannot be dispelled, neither by friends nor by enemies, except by invulnerabilities such as Divine Shield or Ice Block.
Can be "chain" casted from target to target to potentially scout instances for rare mobs/patrols.
A mind-visioned rogue or druid who stealths can still be seen, and even hit with an instant cast spell. Any normally cast spell will interrupt Mind Vision earlier than the new spell hits, causing a loss of the target.
If your target does not target anyone, this spell causes them to automatically target you.
