Supporter gets 1 skin per team when they're added and a bit of perks over regular players like 1-2 chat colors, name color in TTT, small other perks in DarkRP. This seems kind of decent in terms of perks you keep permanently and they never go away.
It's not meant to be something you strive to achieve, it's now meant to just recognize those who have donated quite a bit over their time here at SG. I'm confused by your comment about 13 year olds who don't have PayPal or a credit card, because you need to donate $20 to get Supporter in the first place?
The only thing we're moving away from is giving good perks permanently to a rank that never goes away after you donate a rather miniscule amount in the grand scheme of things. Instead they now just get kinda decent perks permanently while those who choose to donate every month will be rewarded substantially more for their continued commitment and support for our community. Instead of donating once for $20 and basically having everything they care about and it never goes away.
