tl;dr: New force sword type that has “defenses” instead of “warp resistance” which is functionally the same as a force sword with 0% warp resistance.
!!!
Post Scriptum:
This all being said however, I truly think the best solution still would be to just allow for reducing of stat-%, that would help with staves and certain weapons that do not want to stagger, for example some rifles with collateral, as stagger can throw enemies of of the line of fire.
!!!
After considering that the developers flat-out refused to allow players to reduce or refrain from upgrading a (set of) specific stat-% in the crafting system, even when this was a sensible request by many a skilled player and which could have been implemented, I think I have a solution to at least the issue this decision causes for the force swords.
To have the cake and eat it - so to say - for the developers, who seem to be blind to the fact that warp resistance being high is a bad thing, I suggest an addition of a new type of force sword in the game, which allows for the psykers who like warp resistance on their swords to keep it, and allows for psykers who want to keep their warp resistance low to “keep it low”.
The introduction of a new force sword mark, named for example “Warp-Open” (instead of Blaze)
“Warp-Open” forceswords would not have Warp Resistance as a statistic, and their Warp Charged special activation would always cause the psyker to gain 45% Peril. They could have a stat like Defenses instead as placeholder for the removed warp resistance, but scaled so that at 60% defenses the Warp-Open swords would be equal in defense-stats to the current Blaze forceswords.
The swords would have the similar treatment of cosmetics as Rumbler and Kickback, which is to say they share the Cosmetics between them but may have a different flourish on them, such as in this example the Rumblers having the front sights, which Kickbacks do not have on shared skins.
@FatsharkStrawHat I would be glad if this was forwarded to the team, I sincerely think this is the most easily achievable type of compromise in this situation, and I daresay it requires quite little devtime, but has massive benefits for the amount of gameplay enrichment it provides.
