New Payment Option (Opinion?) (Patreon)

Just a while ago, I received an announcement from Patreon about the Charge Up Front option.

First of all, let me explain a bit about the difference between the old payment system that I still use, and this new Charge Up Front option.

With the old payment, new Patrons will get immediate access to exclusive contents as soon as they decide to be my Patron. They will only be charged on the next following month.

Here's the issue: if the new Patrons decides to stop their support before the month ends, they can get the rewards without paying anything. 

Honestly I don't mind about that issue because I believe all of my Patrons have good intentions, but I can see why Patreon team is concerned about this. Having new Patrons getting reward without paying anything is also not fair to paying Patrons. Afterall, being fair to both Creator and Patron is what Patreon Team aiming for.

With the Charge Up Front, new Patrons will be charged before they can get rewards.

It's a permanent feature--meaning if I change from old system to the new one, I can't return back.

Patreon is encouraging Creators to upgrade the old payment system to the new Charge Up Front, but I'd like to hear my Patrons' opinion about it. Should I do it too?

note [1]: because I'm still using the old system now, to prevent the issue I wrote above, big rewards such as Dakimakura printables and NSFW will be delivered after Patrons being charged for July's service. >.<

note [2]: There will be a change of reward list per tier. There will be no raffle, but instead, EVERY Patron of 20$ tier can request colored close-up sketch from me. This includes former patrons. I will announce the detail soon.

note [3]: Even if you decide to stop supporting me for any reason, I will always send monthly gifts! Not as much as rewards for active Patrons of course, but I will make sure all of my Patrons get appreciated, now and forever.
