Aion - pretty summons. Well - aside from the high level water pet that looks like an alien. Give me my seahorse back.
final Fantasy IV- Rydia was the first Summoner I've seen in any game. Impressive summons - were my favorite spells. I wish the summons in this game rocked.
Also summoner can use a whip - yes please. And Rosa the White Mage using a bow. I'd love to have a healer class / archer hybrid.
Final Fantasy Vi - Characters with personal issues I could relate to (or could when I was 12 lol). The cast in 14 feels too hokey and seems to have no lives outside of the plot
