The titan bundle is pretty good in my opinion but in addition to that, there should be a cheaper package like $7 to $15.
From an economic stand point, each people may have different willingness to pay since not everyone is whale and some people want to be casual but also want to spend some small amount of money. $27 is considered to be a lot especially to people in SEA so a lot of people refrain from paying.
If p2w is a concerned where a person might buy both (or more than 1) package, dev can make it so you only be able to buy one option.
I'm saying this so hopefully dev can make more than one package for the christmas event.
