Possible ways to PROPERLY change Tristana

Nerfing Tristana's base AS and making her more reliant on Rapid Fire doesn't do much to her in the big picture. She still gets 700 range at level 18, still has that super long jump, and still has Buster Shot (which can't be dodged).

There needs to be some changes to Tristana in regards to her functionality. Here are a few of my thoughts:

1. Change Buster Shot to a skill-shot, thus making it capable of MISSING.
2. Change Rocket Jump to only reduce the current cooldown by 70-80% (like Master Yi's resets) when she gets kills/assists.
3. Change her base range to 525 from 550, and make Draw a Bead increase her range by 10 with each level. (You end up at 705 range at level 18.)

These would add less safety to her early on (less attack range than on live at early levels), make her dives riskier, and makes her ultimate lose power as a guaranteed self-peel. Other buffs/changes could be given to her to compensate.

Note that these are all just theoretical changes, so take them with a grain of salt.
