Hello, I would advise against starting a new character (and calling them toons). For the most part, your inventory is going to be full of near useless items, this is what I've told every returner the past few weeks and I have yet to hear a complaint. Don't know what it is? Either ask or just sell it off to an NPC. Blackmage is the same as it used to be, you'll remember if you play a bit. Attack with fire, recharge with ice, it's a simple concept it just has other bits and bobs to weave while doing so in later levels. But you can just start a new class at level 1 on the same character without losing story progress.

However since you already created a new character and you're enjoying yourself, why even ask the question? The game is supposed to be fun, so have fun with it! Do what you enjoy, even if that's repeating quests. You will find very quickly that you are actually pretty under-equipped on Glithial Zaine, and your new character will likely find themselves in a better position in the long run.
