Tristana's W reset reduced to a percentage?
I think this could actually work a bit as a small step to nerfing her safety and snowballing potential - if her W doesn't immediately reset on kill or assist, there's actual time to respond to her diving into the danger zone and putting her life on the line. Instead, make it similar to Yi's ultimate passive where it's a 70%-80% CDR reduction on her W after a kill or assist. This will at least make her manageable and make her think twice about where she's placing herself before just diving in balls deep - and it'll actually give enemies the ability to react to her without being on such a short timer whenever she decides she wants to dive right on top of a squishy and try to blow it up in two seconds without repercussion.
This would at least be something, and it would be far from dumpstering Tristana.
allow them to skip an entire item pretty much enabling their late game sooner and making their late game even stronger. Its also the barrier heal problem that basically make ADCs impossible to kill especially with a janna sorka around.
