When there’s a three day event with three different rare dinosaurs, 15 attempts in total, it’s actually very hard for me to get all 15 attempts done. Yes, there’s “plenty of time”, 3 days, but unless I spend all three days going to different parks at different hours, it’s hard for me to even get 5 attempts at the dino I want! These past weeks I’m actually losing some attempts because of this. I can’t spend all that time hunting for the ones I want, and specially these last days, the heat is so deadly I can’t really go outside during the day.
If the new events are supposed to let us choose - then let us choose. Just let us select which dino we are hunting and have that one spawn for us, like the OP suggested. Either that or greatly increase the number of park event spawns we get. As it is now, it’s not really working, even if the initial idea of letting us choose was good.
