Benefits to pro and subs in channel leveling
Adding benefits like more hearts given for actions in channel leveling to Pro users may give more incentive for people to purchase it. Also, giving additional benefits in that regard to subs to a channel. Much like it is with sparks earned and leveling your account on Mixer for Pro. From what i have seen people saying, there just is not enough benefits to Pro right now to justify paying for it for some.
Ex. A user without Pro or a Sub to a channel would earn 100 sparks every five minutes. A Pro user would earn 250 hearts in all channels. If someone is a Sub to a channel they would earn 300 hearts and if they are a Pro and a Sub in a channel they would earn 400 hearts.
Just a thought.
