Zz'Rot Nerf Thoughts... Make worth more than 25g? 100?

First let me say I do enjoy the item. I think it has added an entirely new layer of strategy for map pressure (and even wave clear to a point) and is just option to use for your team.

HOWEVER, the item is very NOT fun to play against, especially when the other team has multiple 'Rots. There seems to be little counter play to the mechanic, especially in an even game. You either know where it is and can't get to it safely due to fog of war, etc. Or you don't know exactly where it is and would have to search the fog of war. And then, once its found, it can take a very long time to kill depending on your champ.

So thoughts on the nerf... I'm not sure you can change the effects of the item active without rendering useless and I dont think thats whats best. But what I think IS a viable option for an indirect nerf would be to make the Zz'Rot worth more than 25g once destroyed. I was initially thinking something in the ball park of 100g, and this effect could scale with game time. I could be jaded, but it just seems that generally the teams can get away with putting rots on one side of hte map without needing the protect their presence with little to no reward for destroying since the active will be up again shortly once you do have it destroyed..

thoughts? bad idea good idea? let me know what you think!
