Stacking Static Siv needs to be nerfed...

I had one game I played earlier where one person stacked three static sivs on Varus and since siv multi hits, having three sivs on one champ is a bitch to deal with. I recently played a game in rank where I was able to build two sivs, so I decided to build it onto Vayne and basically she alone pretty much did the most damage. Considering that building siv as a primary form of damage is almost a must for most players in the current meta, I do think stacking of siv then needs to be nerfed and or only have it so you can build one siv for each champ on the board.

Now I mean if you have an assassin and decide to back line the ranger or slinger, it's alright, but some people due build sivs onto tankier champs...
