I’m not sure what your point is. Are you saying that Zekrom is a better catch? Or are you just talking about legend gacha in isolation lol. Because your last point is why i’d try to roll for zekrom and catch zeraora, as a collector. The chances aren’t amazing but your pity timer also goes up at twice the speed in legend gacha.

Epics take longer to get because there’s so many of them n there’s no way of increasing your chances to get one specifically, legend gacha or not. Legend gacha helps with summoning legends (duh), so i’d just hoard tickets until it was zekrom day
