That's it! Crit Rengar is gone!
If one were to look at the "critical strike" items, one would find that only these (final) items are available to a melee champion on SR. IE PD ER RFC Statikk
Annnnd of course TRIFORCE!
Triforce has great synergy with Rengar!
So, what should Riot do? Ruin it by entirely removing Critgar.
Out of the available items as of Triforce's change to an (IRELIA NAD JAX BUFF), there are only a few which suit Rengar.
Staple critgar items -

Now, this leaves us with two items available to melee champions - ER and RFC. RFC will be worthless, as it will not do as much damage as the Statikk and will not stack. It would give the 100% critical chance but would mostly be wasted. ER is the only somewhat viable choice, as it gives AD, CDR, and Crit chance. However, the mana s a large part of the itme, and all of the item that relates to mana is wasted. In addition, the new triforce makes crit Rengar give up the Sheen, Phage, and full crit that synergized so well. There always has to be a critical chance sheen item for assassins like Rengar - OH WAIT! Riot hates Rengar! They want to buff Irelia and Jax! Also, why not throw in Illaoi as yet another viable VOLIBEAR 2.0?
way more (200% ad on next auto after using ability)
The CDR i feel is for constant DPS so you can get Q of again and again, But for me it would be waste because i want 1 shot not DPS.
