I was under the impression that the Horn was disabked due to the glitch that enabled it's power to effect minions spawned after it's use. If the glitch has been corrected, I don't believe the item is outside the realm of acceptable.

ring was bugged because once activated, then dying near the citadel, you minions would hide inside and attack the citadel.

Since when did they come back

I cant seem to find these OP items

This is WIN.

i.e. freshly summoned minions used to appear with the buff from the item active on them, without the item being used. so minions spawned by generals were invincible for 10 seconds after spawning, then another 10 seconds upon activation of the item (in the case of horn of battle). pretty imba for taking out structures.

apparently it is fixed now though, haven't bothered to check yet ^^
