Pro, TONS and TONS of LOOT!
One of the pros of being VIP is also one of the reasons people get VIP in the first place. Getting TONS and TONS of LOOT! This picture showed 999,999 SC and 999,999 Diamonds! I got years VIP only for this reason and some snazzy rares. ;-)
Con, beggers!
Being a VIP myself, I've had to experience people begging from time to time. They'd beg and beg for greets. I once even saw a girl post an AB saying she got VIP. I looked in the comment section and two people said, "Gimme a greet" or "Please give me a greet." Like.. greedy? Much.
Pro, getting VIP clothes!
Non-VIPs, I know you're reading this. Why do you want VIP? Oh, you want to get VIP clothes, you say? You're sick of being able to buy hardly anything, you say? I can relate. I've been Non-VIP before. It's so annoying! And some people want to stop that and just be able to get what they want. It's such a relief when you get VIP and are able to get clothing to your heart's desire.
Con, being a possible hacker target.
Nobody likes getting hacked, but when you're VIP it seems to hurt more. Why do you ask? Oh, maybe because you wasted your hard-earned money on a game. Y'know no big deal just about $80 dollars gone down the drain. NO! NO NO NO! You die. Not only because that account had D Pack rares, but you/your parents wasted their/your cash. Like who likes getting their cash away for no reason? I don't. My mom stole $50 from me... I'M ALWAYS GETTING SIDE-TRACKED!!1!!!1
Well, you wanna get VIP now? Yeah? Oh.. okay.. I thought you were gonna save that cash for me... Mkay.
BUH-BYE! :-)
