The points required to get even one star in this event are kind of ridiculous. Maybe it would be less so if we didn't also have a raid event going on (meaning the budget doesn't get stretched so much between buying different bundles in order to have enough brew in addition to getting extra dragon food to level up your dragons)?
The points for tooth and scale can be ridiculous, but so long as your alter/spires are maintained at high levels and your dragon xp research is kept up, you shouldnt have a problem feeding your dragons enough to rank. 👍 I think i have seen an ultra tooth and scale before but dont give ATA any ideas. I personally feel ultra events are over used.
