Categorizing/updating champions based on the role they actually play.
I think there needs to be an update to all champions about whether they are the "tank, fighter, etc. " that they are listed as. Here is Riots original descriptions of each. I think there are quite a few discrepancies with the current line up.
Mage: Mages are mostly ranged champions who prioritize powerful abilities over basic attacks. Typically mages are characterized by some combination of long-range, area-effect or high-utility spells to get the job done. A skilled mage can have a huge impact on any team with their versatile skillsets and flexible play style.
Tank: Tanks are durable, front-line champions that help lock down enemies and start fights. They're usually found leading the charge, choosing the right times and situations to initiate aggression. Many tanks can also protect their more fragile teammates by stunning or pushing around dangerous foes and limiting their damage potential.
Fighter: Fighters are close range combatants that possess a mix of offensive and defensive capabilities. While they don't have as much utility as a tank or as much damage as an assassin, a fighter's damage will add up over time to make it a major threat. Each fighter has a unique blend of mobility, damage, disruption and durability.
Support: Supports make plays by enabling their allies through buffs and heals, or by disrupting enemy lines through crowd control. From laning to late game teamfights, supports create advantages and opportunities for their teammates to capitalize on. A skilled support gives their team the edge it needs to claim victory, and can turn the tide of battle with just one well-timed play.
Assassin: An assassin is an agile champion that specializes in killing or disabling high value targets. Focused on infiltration, deception, and mobility, assassins are opportunistic hunters who find favorable moments within a fight before jumping into the fray. Regardless of the size of the enemy team, assassins specialize in positioning and artful killing. They strike when the time is right – no sooner, no later.
Marksman: A marksman is a ranged attacker that sacrifices defensive power and utility to focus on dealing strong, continuous damage to individual targets. Typically focused on using their basic attacks more than their abilities, marksmen have the capability to scale and deal out devastating levels of damage in the late phase of any game.
It is my opinion that the category of Fighters needs to be revisited the most. This makes it sound like any champion that is melee is a fighter. Can we get more specific and then update the roles of all the champions?
