Kircheis Shard is kinda worthless
I haven't seen anyone build this item or I haven't seen any tips and tricks with it. I think its kinda worthless to build it and IMO cost way too much
I think it should get new passive or big price reduction from 750 to 550 or something like it. Also why would it not benefit vs Jungler monsters? Currently it does 40 damage at 100 stacks but i think it should do 120 damage to monsters and minions. I think at least this way it be somehow more useful. The way i see it is that it should not deal too much damage vs champion but at the same time i don't see what is even the point of getting it.
I am building Statikk shiv on Yi Every game but i cannot benefit from Shard at all in any way. Its way too expansive and is not worth getting Shard before Zeal. Like i said no one ever shown any tips and tricks with it. But i think its should benefit vs jungle monsters a bit more or at least replace the current passive with new one like you did to Serrated Dirk
Some people would say - BUT HOLY SHIET DOOD THE COST EFFICIENCY!!!! it might be the most cost efficient item in the game but if it doesn't have any usefulness or any power efficiency what the point of getting the item at the 1st place?
and benefit from it with movement speed but getting Shard is not worthy and for me this is big problem
or 
I would probably always go zeal first because he's melee and gets more damage out of the movespeed buff than he would the occasional onhit unless he's already got like 2.5 attack speed + boots. In some cases on melee champs 
will give you more damage than 
as they require a greater variety of stats to succeed where ranged can just focus on a few to do so.
gives a small amount of 3 different stats as opposed to 1. Almost universally better for melee champs
vs 
. Now thats actual choice
and a bit more than a 
. On melee champs 9 times out of 10 you will want this first. and that's just being generous and assuming there is some melee champ that gets more use out of the other one.
and 5x 
and still be 50g underbudget. Everytime the charge is up I can hit a minion ONE time because I have to actually deal with wave control unlike a jungler. Because I use this instead of hitting minions multiple times using zeal because the crit didn't go off when I needed it to or because I DID crit and now I've dealt too much a minion under tower I am not going to be worried about master yi and his zeal or whatever. Because I have better control and my csing is on point. Occasionally I may use this for poke, I don't expect to get many hits in. What good is zeal if you attack only once and don't crit? It does almost nothing in that case, you save .01 seconds on your single shot harass and lose out on much cheaper onhit offdamage.
