Class Speed Differences, Beyond Simple DPS

Damage calculations always take into account Skill delay and is reflected in DPM. Mobility and ease of use is a different story. the reason why you cannot easily calculate that is simply because of too many extraneous factors such as how a map is oriented (e.g some class have high jumps, and are more successful in vertically oriented maps, attacks have different ranges). At that point is just semantics but no real calculations can be done because of not being able to standardize the skillset, as the average KMS player is probably more skilled than the average GMS player.
