Actually, i do think he can use some buffs for his lane, especially in terms of survivabillity.
Though the buff is pretty small, the manaregen is just cleaning up numbers and not actually an improvement( ~0.22 more mana every second at level 18)
I personally would love to get his old Base AS back, it would make his AAs feel more responsive and quick(as an assasins AA should) while giving him a bit more threat to finish targets once his combo is down. I really don't understand why it got gutted at all, assasins already lost the 40% on yomuun's, it's not like high base as would alow them to do anything stupid with their items, while high base AS would be fitting for assasins and makes them feel more fluid.
Though what i'd prefer the msot would be some buffs to his W. It's far less reliable than be for and even has less imapct IF it lands.
A slightly higher range and bigger aoe wouldn't hurt.
I's also prefer the return to be delayed even slightly longer, but therefor haveing a slow on the first hit aswell, like 25% for 1,5sec on both hits, stacking additivly(so 50% if both hit)
Some more base ms, or an ms-buff after dealing damage with Q to an champion would be nice, the 15 ms nerf off the reworke did hit him quite hard.
The lack of reliable ranged aoe, and mostly of a reliable ranged slow made talon even more binary. He just has even less to offer for his team than pre rework if he can't get off a clean assasination.
