So today they released a high level update to Herblore. While I'm not able to use it yet, it sounds great. The new potions look to be great benefits to combat. Being untradeable may turn some people off, but I think it's a good addition. It's a reward for those who train the skill.

There needs to be more content that rewards a player with exclusive rewards. Yes, everyone wants to train skills to sell rewards from it (whether it's a resource, produced or npc drop). But where is the individuality if everyone can obtain/use everything in game without putting the time and effort into training to get it themselves.

Aside from that point, if this is a sample of what's to come in other skills future high(er) level updates, I'm pretty excited to see what Jagex comes up with.
