Instead of nerfing the distance zzrot can travel...
How about change voidling's damage to both towers and minions based on current health?
Your aim was to quote: 'However, we also want ZZ’Rot to be an engaging item that informs a tank’s playstyle, not something they fire and forget.'
and changing a voidling's damage based on hp is a better option, i reckon, than just increasing the decay rate. Why? It makes you think about placement rather than plonking it down in any decent spot.
If the zz is placed far away from the enemy base, it's safe but it isn't very effective as when it reaches waves or towers, it will do very little. Putting it a bit closer makes it more likely to be found out but rewards your risk with the increase damaged. Therefore there's actual strategy in placement which is what I'm presuming you guys were after, right?
What do you guys think?
