If crit will act like that, players at early game will get crit runes and stuck attacks until they have next 100% crit attack and poke enemy with it. Maybe junglers will stuck crit too before gank. It will turn gameplay into something new, more complex and will result in more fail acting, witch will just ruin interest, in my opinion.

GP now OP, he stacking crit and Q poor enemy.

Meanwhile Phage (without randomness) and crit will be totally incompatible, because it will be very hard to stuck them both (shifted stacking of both same "chances"; different chances, which hard to synchronize).

If crit will act as multiplier of damage, ad carry become less scary, because u can calculate flat damage over time, which they deal to you and escape in time.
