Lets work out some scenarios:
vs Janna, Karma, Tahm, Morde, Shen. Those have shields with some different meaning then just so small shield on a 4k hp tank. Technicly morganas shield is bypassed, but i assume the "cant be cced" is still activ while the shield gets bypassed.
Ok, lets look at Janna:
Janna is a peeling monster. Her R provides knockback while her e gives fast survivalbility. If a tanky diver/tank support, manages to get close enough to use the activ, they and the rest of the team will be knocked away, thus will not be able to make use of the "by pass" duration, since they are not in range/cced. Only something like olaf would make use out of this.
Karma:
Karma is a high team mobility champ. If you manage to get close enough for the activ, the hole team will get speed up. So your dmg carrys will also not be able to make use of it. Only if you have a heavy CC chain (malphite ult + ori ult or so) then your carrys may can make use of it. But you normaly dont have a high range cc lockdown, or the squshiys will already die from the dmg of these and the activ was technicly not needed.
**
Tahm**:
Tahm is a rather special case. He actives his shield only if he has basicly no hp left. He does not have escapes or movements speed, so you can stay on his butt. This item technicly completly removes everything tahm is balanced around. He does not have mobility but huge ass survivability because of his shield. But if you can simply by pass that with an item, that is not so good. Riot nerfed QSS because it was a direkt counter to some stuff, Your item directly counters tahm, and not just a small counter it completly destroys him.
So you have my word that your item will never be introduced into lol. Atleast not in this state.
Morde:
This would also heavily nerf morde since he is also heavy balanced around getting lost of shields. The 2sec duration might be not super bad, but is still is a rather big nerf. Special if you have long range dmg in your team so the tank locks morde down while the carrys burst him.
**
Shen:**
Shen is famous for safing his teammate globaly at lvl6. further into the game his shield becomes pretty big, and he gives himself quiet alot of shields. But this item will completly screw his ult making it useless. It is balanced around the time he needs before he arives. If you can destroy shens shield and the rest of the enemys hp then he ult was wasted. But if he ults and his huge shield gets nullifed for a small timeframe his ally is guaranteed to die before he arives.
This also is a very big counter to shen.
**
vs adcs/Squishys:**
You basicly destroy shield based sups/tanks but how effectiv is this vs the adcs/sqhishys, the ones that you want to target?
There are 2 very effectiv ways to kill squishys/adcs.
- cc lock them
- burst them
A cc locked adc is dead if he does not have QSS. The small extra shields will be taken with or without the ohmwreckers activ they will not change the outcome, so the ohmwrecker activ is useless.
Burst is a little different, it depends on the total dmg and the timewindow. A big window makes shielding possible, but high total dmg still negates the shielding.
So only if the "burst" is predictable (an engage) and the amount of it is not high enough to kill the squishy and then the tank that has this item and can get near the squishys. Then and only then, will this item be usefull.
And only engage tanks (senju, amumu, zac, malp etc) or engage sup (leona, ali etc.) would buy this.
#To sum it up:
Nice idea, but it totaly breaks certain champs and the target audience does not increase.
To atleast not break certain champions, the "shield bypass" should be changed to ether shield are only ~40-50% effectiv on the target or shields take 2times the dmg.
This item would max. only be bought to counter shen, tahm, morde, karma and that is a) unfair for them and b) way to small of a reason to make this item.
Lastly Ohmwrecker basic identity is interacting with towers. Changing/removing that will not happen, only if theres no other way! They would rather introduce a new item then stripping such a unique thing away.
Yes i know Ohmwrecker is not in a good state currently but i dont think that this would be the right way.
There are serval post/discussions about Ohmwrecker. Even i did only recently a post about this item.
