As sad as it may be, Myth is only good with PvP. They only have 2 AoEs, and pierce, shatter, earth, minions, only good for PvP. No disrespect Conjurers. I would totally have a Myth char if it was better at PvE.
I am a Diviner and I have mainly Myth and Balance as secondary schools. I don't see many Conjurers. Why? I like Myth!
i dont think people know that there is more to myth then just minions. I believe people dont have myth wizards because they think its all about minions. The perks arent as apealing as high health and defense (ice), healing abilities (life), unbeatable strength (storm), healing and attacking at the same time (death), overtime attacks that can give tons of damage after going through a shield (fire), and no there is no such thing as a balance shield and balance gets the feel of every school.
But when you look past the large amounts of minoins myth get, myth is actually a pretty chill school. it can remove all blades and and shields from your oponent using earthquake or shatter. it can shift any overtime attack back to the enemy (which is awesome in tower of the helaphant if you fizzle :] it helped me tons).
So basically people dont see more to myth then the minions. But i think a myth wizard is awesome to have at your side :)
Myth is ignored by basically everybody. I have a Myth Warlord, and I still get ignored >.>, but PvE is way too easy for Myth. Also, no good AoE damage, every class in game, has a good AoE attack for offense. Myth, is well, you know, ignored.
