If I was in charge.

Magicians ought to have received their own version of Highsun, giving them an "oh shit" button to make up for their lack of CC. A second version of CotH would have been cool too, one that allowed magicians to summon themselves to any group member in zone.

A druid version (Call of the Hierophant / Wild) could have summoned group members as long as they were in wolf, bear, or tree form.

A necromancer version (Call of the Antihero) could have traded locations of the caster with another group member, while also swapping aggro both ways at the cost of a black pearl. Either that or the ability to CotH group members in skeletal form. AoN and Shroud of Undeath have added value. Chill/Ignite Bones would have had another use on raids other than irritating everyone.

If nothing else, these additions would have sped up the CotHing process.

Also, overpowered or not, the mage epic pet should have been all four elements combined. Either that or two elements combined at random for each summon. Ex.: Earth and water form as mud. In addition to previous innate abilities of both original elements, it can blind targets.
