When deciding on Deadly vs Battleforged, you should go with Battleforged. It's superior to Deadly, which only affects the damage and accuracy of the Ravage ability. Once every 2 minutes is a poor idea for a tech kit... Battleforged adds 50 tooth&claw (which adds accuracy and damage to ALL t&c attacks) plus the +10 damage delay adjusted, again to all attacks. Which means it can help Gold Rage.
Currently Deadly is bugged, but even if it was fixed, it's not worth using. If it affected all attacks, then it might be an interesting option... but then it would be nearly identical to Sharper.. Even if Deadly was +100 damage delay adjusted, it wouldn't be worth using for an ability you can only use once every 2 minutes.
I recommend they re-work it into something different than a tech that only affects ravage. Make it a spellcaster claw tech, +100 primal, +15 damage delay adjusted to all spells, +50 accuracy. I know a few spellcasters who would love something like that.
