is more a splitpush item than a siege item, the voidlings don't really tank turrets and they are easily cleared by defending players.
It's usually used to push out lanes and force people to defend their tower in an else empty lane alowing you to have a number advantage elsewhere on the map.
Or to help a lone tank killing towers while pushing.
However, we do actually have another siege item, one with a very similar funktion to the banner:
THE BANNER!
However, i think there is room for more.
One could change the current banne
r to place the siege-banner
instead of buffing a single minion, and changeOhmwrecker
to buff a single minion with a buff depending on the minion:
- Meele gets alot vs towers/minons and aoe aswell overall more beef and taunts towers, so you can use it to 'disable' turrets and the counterplay would be focuseing the minion down(it should be not that much more tanky vs single target stuff)
- Ranged gets a multi target attack and alot more dps aswell as a spellshield and slightly increased range, so it helps alot at clearing out minonwaves and is somewhat resistant to ranged waveclear
- Siege becomes a ballista with high range and bonus damage vs towers, and extra tankiness, maybe aditional damagereduction vs aoe, forcing your opponents to eventually engage on you to clear that minion befor it slowly grinds down their tower.
this would make it a versatile item for wave-controll and siegeing.
You could buff a ranged minion to answer a big minionwave aproaching your tower without beeing there in person, you could buff a meele minion to take down a tower safely or setup a dive, or to create a slowpush on a sidelane, or you can use it on a siege minion to force a team to stop their turtle and engage on you.
