will there be a x % crit unlocked at 10 minutes rune?
according to meddler, there wont be a crit rune anymore that grants a small amount of early crit chance. this is pretty reasonable, considering how toxic low % of very early critical strike chance can be. a series of lucky crits can easily translate into an early kill and a massive lead in lane.
however, some of the new runes are going to have a mechanic that unlocks their stats flat at the 10 minute mark.
Discipline After 10 minutes gain 10 Armor and 10 Magic Resist, +2 of each per nearby enemy champion. Range: 800 units
for example as one of the new rework runes.
the great thing is, since these runes are a midgame investment and dont give you anything until the stats unlock, the effects can be made equally powerful once they do come into effect.
so will there be a similar rune to get a decent chunk of critical strike chance unlocked at 10 minutes? maybe even scaling off another stat. like critical strike chance equal to your total cdr. (just an example)
i just hope there will be some way to grab some extra critical strike chance that is not attached to attack speed.

maybe one of the bounty hunter runes can give you extra crit.
After 10 minutes gain 10% critical strike chance, plus 4% for each individual takedown on an enemy champion
could make one of the bounty hunter runes.
