I had a similar daydream with this build path, simply because you'd make the tri in triforce more towards three passives rather than just three components. I love the idea of the shard being apart of triforce, but I have no idea how it would actually turn out if it went live. I do wish that Riot would find a way to make trirorce more of a critless damage purchase and make a seperate sheen upgrade with crit chance for Corki and possibly Lucian and Vayne. The only things I am afraid of with this iteration of Triforce would that it would provide a REALLY strong mixed damage burst which could easily shift the meta if the numbers are too high or if it's just too low of a price for what it gives. Conversely, it would also open up the item to a wider variety of champions than just fighters (assasins, tanks). I honestly just love the idea of Triforce being less of a crit item and more of a burst item so that it's more enjoyable to build on more fighters and other classes. The double sheen proc seems too crazy whilst the 60 ms from an energized attack would have a lot of value. I know a lot of people wouldn't like the movespeed to be gone, but it's a small sacrifice if you want to remove crit from Triforce. If something like this ever were to come out I wouldn't really expect it until maybe preseason where Riot really likes to experiment with new ideas. I know that Riot tried an iteration with Recurve Bow which didn't turn out well (It sounds really week in general just thinking about it because Triforce should be bursty in nature). The Shard needs to be considered to give tri the critless justice it deserves.
