I honestly think that this is a great idea, so you don't lose out to someone who is possibly faster at clicking then you are.
It shouldnt majorly impact skilling because every player now has easier time skilling. It makes skilling alot easier and prevents skilling from slowing down, caused by missclicks etc.
Agility - Just move your character close to the obstacle and it automatically jumps over it.
Thieving - Just move next to npc you want to pickpocket, and it does it automatically for as lõng as you're next to npc.
Woodcutting - Just move next to a tree, and it chops it automatically.
Mining - Just move next to ore, and your character mines it automatically.
I think is a great Update, because many of the players dont know how to skill and even if they do there's people who do it better than them, this makes the game fair.
Let's add this ingame so Thomy can get feedback on this feature.
