Fighters are going to keep feeling less than idea ult marksmen only outscale them at 4+ items.

Marksmen still have a 2 to 3 item power spike.

Marksmen use to be a late game investment that was good for some siege from a distance.

There however has been on spicific change over the years that has had mages encroach on marksmens siege power. In 1.0.0.72 the ap ratio damage to turrets was increased to .40 from .25 ap and today it sits at .60 ap which has drastically sped up turret killing speed. Yes that has drastically speed up laning phase and made mages arguably better at turret killing than marksmen.

To keep marksmen as worth picking their power spike has been moved up in the game. This has resulted in fighters having to get more powerful tools to stay relavant and tanks are getting more damage due to fighters getting more tools.

Effectively tanks are often times just easier to consistently perform on fighters with how much their damage has been increased and the lack of effectiveness on defensive stats with the speed up of marksmen scaling.

Mages also have their damage upped to stay relavant compared to everyone else. Fighters end up having to be assassins who can take a hit meaning a comparable kill time to many assassins while having no built in escape.

Perhaps it is time to lower the AP ratio against turrets to .30.
