1. Nope.
2. It is indeed a bit outdated but not like it's useless now.
Some stuff with team building aren't correct anymore, but like I said it's outdated. e.g. his MT recommendation for fire or dark...
- Fire Dakki/Uriel/Ares... it's obivous go with Uriel > Amaterasu/Mars > Dakki/Ares
- Even max burst for wind is wrong...
- For thunder... you won't use the next MT for Mammon if Baal U is already out.
Next year it will be useless, especially the MT recommendation. Because meta is changing for most of the elements anyway and you are getting better KHs option to use a Miracle Ticket.
Tbh I wouldn't use his Miracle Ticket or rather his team recommendation as template for the next Miracle Ticket anymore.
Because future KHs are missing, some MT prioritys aren't correct anymore, healing isn't necessary in end game later and some other stuffs.
