Hey, I also came here from the Reddit post the other day. I'd totally be down to join these themed TFs! My alts aren't as high-leveled as I'd like them to be, so my ability to attend these might be limited at times, but I should be able to make most of next month's, save for maybe the all-dark Ice Mistral (my dark/fire blaster is only lv 24).
Actually, that gives me a question: for these "all [element]" themes, like this upcoming all-dark Ice Mistral, do we have to have dark/dark specifically? Or is it more just having an overall 'dark' theme? My Dark/Fire Blaster, for example, has dark themed fire for their secondary.
