Tristana Needs a new passive
Tristana has no reason to not have full attack range from the start. Her pre level 16 game is so terribly weak that shes almost 100% reliant on a team that is capable of either gaining her the lead, or having an over all lead for her to be successful.
Sure she has decent mobility, but until she reaches level 16 her attack range is pitiful enough where any other ADC can easily go toe to toe with her while having more power in their aggression than tristana has.
Her W as an ADC is used almost exclussively as an escape tool, her E is used almost exclussively as a pushing tool until later on when she can actually properly proc the stacks on it on an enemy to make the burst at the end effective, but without her level 16-18 attack range, she puts herself wayyyyy to close to danger in order to stack that making it essentially worthless until later on.
Her attack speed steroid is very nice but lasting only 5 seconds on a much longer CD makes it sub par to steroids like say twitch who comes with a stealth giving him a HUGE advantage in similar scenarios.
Her ult has no use as an ADC other than to help her kite, which in some cases isnt even enough with her W combined.
She either needs her max attack range earlier on to make her more relevant, or her ult atleast needs either AD scaling OR some kind of execute type feature to it.
The reasons she was OP towards the begining of S6 was more because of how items were, but on that same note, other adcs and other champs abused those same items as well so its not really fair to claim tristana as being oppressive during a time when alot of champions using those items were oppressive.
She needs some love... she really does
