If we go by values from first post, then apart from no clue about RNG - amount of trophies is not really that much bigger a.k.a. its not even double what you get in phase one. My calculations from early posts suggest that you can get around 900k to 1000k trophies if you dedicate all stamina you have to the event. You need close to 1m4 trophies thou to fully clear all resets or if you are unlucky and get things you want/red thing that lets you reset as last spins, meaning that it technically is possible to finish event, but without doing stamina refills its impossible to clear everything out.
Compared to last gacha event that had bugged or intended special bonus stages that you could farm, and also that there was no RNG in the event drops farming, this event seems like completely out of place (at least based on few events I saw since I started playing Nov).
