Tbh i think those 10 banns should be given right now.

Would love to ban Rengar when my team forgets to.

Yeah i really dont like what they did with rengar (or any of the new assassins). Im fine with being 100-0'd by an assassin if im caught out, thats my fault. But riot said that these champs will need to have better desicion making in order to efficiently kill their targets, but all this meant was that they could still oneshot carries, but now they have an easier way of escaping also. i learned this when i played rengar for the first time, ulted at level 9, and stil oneshot their adc even using the empowered spell on W to cleanse (lack of dmg)
