Now that crits are weaker.

No crit is objectively weaker. Hence why people are playing bruisers and on-hit adc's in bot lane right now.

Its weaker at every point of the game till high completion of build. we talking 3-4 +boots in items. So its always weaker in early game compaired to old builds. The argument that 100% crits on 3 items and the truedamage is ture, but only after your 3 item build and it still needs more time after that to really shine for saveing you a inventory slot, if the games over before the game length has gotten to the point your seeing 5 or 6 item slots occupied your really overlooking the impact that every single crit item has taken a nerf for all parts of it leading up to compleation. Zeal got more cost less stats. Ie sucks first item, cost more, provides less then old ie in the build did, requires 2 other items that don't add AD, no good AD crit options other then IE. No ER crits. every Zeal line cost more.

Every step of the way old build was cheeper, stronger, and with a smoother build path. So rush crits and its worse every time to old, don't expect to do better in early game because it can only ever be worse then it was. Or build others and remember each items will delays crits by that item and again the entire build path for them is weaker and they cost more. Realisticaly its just not a good early game as a statistic anymore assuming that its not inherent to your kit .
