Most times, your support wizard is only there to help crowd-control the minions, potential boss hits as well.

Me and my buddy got me from ftp lvl 18 to first 48 with my first membership back in the hay day, in under a week. The issue with trying to solo speed run is you need a good aoe spell. Death doesn’t get their first aoe spell till 48. After that, they’re the best school for soloing content. If Vampire was an aoe spell they’d be the best solo class. Life doesn’t get their first aoe spell till 48 either, but they get healing spells, which can help in soloing content. Ice doesn’t get their aoe spell until lvl 22, same with Fire, and Myth, making them pretty decent for soloing content early, where as Storm doesn’t get theirs until 28, regardless it’s pretty hard to solo as storm early, around 100 it becomes super easy if you have Shadow Malistaire gear. Balance get’s their aoe spell the earliest at lvl 16! Making them the king of soloing content early. Along with Balance Blade at 12, and balance of Power now giving bonus balance damage instead of power pip chance at 22. They’re pretty good at soloing content early, but even with Power Nova and RA late game, not having any damage convert really hurts them. The addition of Hyper Elixers help a lot, unfortunately it’s $10 a pop per 12 hours.

TLDR: Each school has it’s pros and cons of trying to speed run solo, the issue is without heirloom gear like in wow, it’s very hard for most schools to level up quickly without paying money, or having a friend boost you.
