i think you should drop the true damage conversion on infinity edge.
i dont know if the true damage mechanic should be replaced with something else, but it doesnt seem healthy.
why not make it additional bonus armor penetration on critical strikes instead?
its like marskmen got quadrupel compensated for the lost 50% bonus on critical strikes.
- 20% to 50% more crit in their standart builds, depending if they "just" bought one or two zeal items with i.e. before
- 10 more ad
- 20% true damage conversion
and then there is the last whisper change, which will make them penetrate about an additional 30 base armor.
marksmen really dont need more damage against fighters and tanks. they just need a nerf of their burst to squishies
the price increase on crit items had to happen anyways, since zeal items just were too cheap for the longest time, which caused marksmen itemization to be 500 to 1000 gold cheaper than that of other carries, which made no sense considering that marksmen outscale everyone.
and abilities in champion kits.
on top of my head.
