"And when Smite is combined with Psychic Leaching and Charged Up, you can quickly restore up to 60% of toughness to your squad by just pressing LMB a few times (with Smite you can turn the charges, up to 3 of them, into toughness pretty quick)."
Yes, I get where your coming from. You’re concerned that limiting secondary Smite attack would limit how often Psychic Leeching can restore toughness to teammates, a valid concern. Hear me out, and I’ll explain how Psychic Leeching will be just as effective at the end.
If Smite secondary fire was limited, it could be given a much more versatile and arguably easier to use function than it currently has.
By making it a linear bolt that is fired without charge up required, Psykers would be able to deploy it much faster, with much more accuracy, and to greater effect as Psykers would be able to use their weapons during the duration of Smite’s stun. The linear bolt would also be able to travel much further than Smite can reach right now, before impacting the initial target, then arcing to surrounding enemies.
It would also be much easier to justify Smite being able to stagger Bosses with the 3 charge limit, which would be an absolute game changer for Smykers who happen to be the last player alive.
We’re talking about using Smite to create priceless breathing room on aggressive melee bosses - an enemy Psyker struggles to deal with on the majority of builds, time that Psyker can use to rescue teammates or get to a safer position. As Smite exists right now, there’s no way Fatshark could allow Smite to have effective stagger on Bosses, as that would be absolutely overpowered with infinite uses.
Back to Psychic Leeching, it would still be just as available as it is right now with Charged Up. Psychic Leeching would proc on Smite primary fire, and primary fire would still have unlimted uses.
