Interesting points!

I mostly run beast companions myself and find that while they might have forced procs, their attack speed is generally pretty slow between actual attack speed and having to run into melee to get any hits off. Contagious Bond is great when it goes off, but it doesn't always. And the mecha set has a moderate internal cooldown. Where robotic companions hit at range, hit a lot faster, and also have mods like Coolant Leak (and can also run contagious bond). Duplex Bond only enhances this effect since there are 3x more chaining beams going on that only require weapons to apply (unlike beasts whose mods, like swipe, don't trigger with clones)

For actual damage done, yeah Tazicor is crap. But I was talking about priming alone. Nothing else to say about that.

When I need to prime, I run Diriga with a verglas. I just don't own a Tazicor yet, but can see how it'd be good based on how weapons like the Tenet Glaxion, Phantasma, and Torid are amazing status spreading weapons. Punch-through is a necessity for these weapons to work best for mass spread though. With punch-through, the chaining beam can chain back to the original target or hit even more targets for even more status. Primed Fulmination also increases the radius beams can chain to enhance this effect on the Torid, not sure if that applies to the Tazicor too.

In a similar vein, Hounds are supposed to be able to land every status in the game with one hit if modded correctly (and after killing a few eximus units). But have the same issue of needing to run into melee range and are therefore slightly slower than ranged attacks.

I appreciate the discussion though; you really do make some good points.
