Making Twitch capable of leashing easier

So I'm hoping this is the place to make a suggestion for a champion, as I've not actually posted on the forums before. But I've been playing a lot of Twitch lately, and there's only one thing that bugs me about him: He cannot leash very well. You're typically only able to auto once or twice and give a relatively poor leash to your jungler, making them take more damage than necessary and possibly even delaying your support from getting to lane with you for experience. No other marksmen has this problem, and I think I have a simple solution for it. Don't allow Twitch's passive to be active until you drop a point into a skill. I don't feel like this would be too complicated for players to understand, and should only take one sentence to explain in the passive tooltip. I understand you might need your passive and skill to harass early on, but realistically you want to wait until that point to level up a skill anyway. With this change at least you now have an option to give a proper leash more often. Anybody have any thoughts on this? Agree, disagree?
