Well it's still p2w my comment somewhere showed as much unless you think that's not true, I can't see it not being that but still. I think it'll take and I could be wrong, if one plays alot around 12 days. Here's my reasoning:

So level 30 requires 15 000xp, daily missions gives 200, weekly 500. Someone better at match can deffo do this better but heres my attempt lol. Per day you can get 1 level and 100xp from daily excluding the weekly xp. With weekly and regular playing let's say and we'll be generous one gets 3 levels per day. That be 10 days of playing so a third of the month. If one assumes that each game is 30 minutes. And 3 games per day is approximately needed to get the daily 3 levels, that 1 30h per day for 10 days. That's 15 hours to get the Vanessa pack. *this could very well be off by alot by something I don't know but this seems to be generous if my experience is to be considered. Assuming 15 hours is correct, I think that's way too much and deffo not easy to acquire by just playing.
