Haven't tried her myself, but my understanding is that she's basically the same speed as Solomon, so yeah, need a lot of outside help to burst fast (FLB Iris glaive helps there if you're lucky enough to get it. EDIT: don't do this, see post below) Medea has insane nukes though, so for stuff like tower it doesn't matter too much that you're not bursting super fast (can only use Mike AW once every 6 floors anyway, and should only save the harder floors for off-element clears.) I'm not sure if ppl use her for MVP racing in rags, maybe if it's super crowded during BT, otherwise I thought Hector is more favored for MVP racing but I could be wrong.
