Would it be a bad idea for IE to have 25% crit, while also letting the Zeal items also have only25%?

A usual ADC's build can lead to either 20+30 (IE+Zeal item, 50%) or 20+30+30 (IE+2 Zeal items)...80%, another Zeal item (unless it's just Zeal) gets it to 110%...or if he forgoes the 4th crit item for an IE, it does equal 100%.

It then becomes 25+25 (IE+Zeal item), or 25+25+25 (IE+2 Zeal items), but it leads to clean numbers and allows IE's crit chance to make it seem like it's being upgraded alongside the weapon.

What this does is reduces the spike from a singular Zeal item (like when Yasuo makes a PD first item, or when ADCs rush Hurricane) by moving that slight spike into IE. It does nerf ADCs late game at the 2 Zeal+IE mark, just a smidge (-5% crit), but if they were to get another Zeal item, it would be 100% instead of the wasted stats of 110%. It also allows more emphasis on if one were to buy IE first rather than the Zeal item, just a bit.
