The shards would be fine if you just modified them a bit.
Remove the scalings (or make them way better), reduce the adaptive force and attack speed ones and yay!
Do something like:
- [4 AD/7 AP], [7% attack speed], [5% CDR + 0.5% per level capped at 10%]
- [4 AD/7 AP], [6 Armor], [7 MR]
- [20 + 15 HP / level capped at 170], [5 Armor + 6 MR], [20 + 10 mana / level capped at 120]
Now you have a 5% instant CDR boost which caps at level 11 instead of level 18 which will actually help out in lane. Also, you have a nice scaling health bonus that feels useful, +15 hp per level is around +15-20% HP gain per level which is pretty nice. It caps out at a reasonable amount as well, at level 11. IDK if the mana is a good option but I think more power should be shifted into the 2nd tree armor/MR shards because right now there's no reason not to take adaptive force (it's grossly powerful compared to the armor/MR). Then in the third tree armor+mr is combined so there's somewhat of an incentive to take health if you're worried about dying, but if you want you can still boost your resistance.
