Houdini was discussed much earlier in this thread IIRC. General consensus was that it was well-received, but I personally do not see it replacing Refractor until Refractor cycles. Getting to 6 using just 1 stealth is nice for DNA, and of course the persistent strength is nice, but with Net Mercer around, I feel like stacked code gates and stealth limitations for Refractor are heavily mitigated.
When Refractor cycles, Houdini will be an adequate replacement though. I do like it in that regard. Stealth is getting significantly buffed from NM and Smoke, I’m alright with seeing their new decoder be slightly (and only slightly) “worse”.
Just my two cents, of course.
