The more I think about it, I like the party actions. It makes my life easier if club doesn't finish a party, because I can still get my boxes.
Sure using DNs is optional but that pop up because I refuse to use DNs (because I used them all soloing) is annoying though. Plus that's 60 DNs a month if this is going to be something that stays in the game. Make it something like AND some PVP actions or something that doesn't technically take real money to get more of.
People in EC clubs, for example, they can't use a DN on those parties (expect during invites). So they're going to be forced to hop clubs just to use DNs for 50 drops most likely.
Someone mentioned it being a bonus for flashers. Cool, but not everyone flashes and the little pop up everytime I hit a party is annoying. And players shouldn't get less for a daily story thing just because they don't want to spend money on DNs or because they're saving DNs for the big promos.
If anything would benefit flashers and people's main accounts and not people's alts (cuz I did see someone mention alts in collectathons), it'd be lite boxes randomly dropping from parties.

I know with my alts I hit parties for my lite boxes and I'm done. That's all I'm doing. I don't want to do more. This change would not motivate me to work more on alts. Whereas on my main I'm usually finishing my daily XC every day. Cuz more parties. So more chances of lite box drop if ATA did that.
