Plasma spamming at close range is not even a good strategy, just something preds do so secure wins in 1v1 or 1v2 situations, otherwise you will be outdamaged by the fireteam. Splash dmg sometimes is not enough, direct hits with plasma shots are necessary, you need to aim for that. The charged plasma shots from far require good timing and positioning to be able to get direct hits. Plasma takes more skill than hitscan.
Disk will depend on how high the sensitivity is, depending on it, its not that simple to maneuver, specially depending on the environment the fireteam is at, can get stuck easily in objects around, you need to move while dodging things and thinking about the position the disk will be on the time the flight will stop to make it come back closer to you and not in a place where the fireteam can easily destroy.
Its rare to get in situations on matches where you will be trying to hit fts that far with bow, most people don’t get to practice enough on it, without practice they won’t get good into doing that consistently. And the fact the depending on the distance the crosshair can get really off doesn’t help much.
