They also explain that that change doesn’t make skilled players have less of an advantage. @MacMan says that what noobs would do is hold down the shield and keep it on, draining their battery and they felt it was useless. Skilled players would tap it right before the monster hit the ally and skilled players thought it was a great equipment.
So they made it more useable, only drains battery when the ally being shielded takes damage. However skilled players are STILL rewarded for using it the more advanced way, while you are channeling the shield, it will not recharge at all. Skilled players tapping it are rewarded with it recharging in between taps, as opposed to noobs who hold it down, they won’t let it recharge.
They made the initial change because noobs weren’t even taking the time to learn the shield gun, this is a pretty good change. Good players have an advanced way of using it but new players won’t feel like it’s worthless.
This is still a competitive game so difficulty can’t be changed around a ton without upsetting the balance between the sides anyways.
