MangaDex comments are just like YouTube comments, it's best for one's sanity to pretend they don't exist. MangaDex at least makes it very easy to do so, unlike the latter.

Warlocks just employ the SaaS licence model, Spellcraft as a Service.
It's actually around 40% uptime with Tek Enchance. It's pretty useless during high mobility missions when your kavat spends most of it's time trying to catch up to you, but during more stationary ones it's pretty good. It's also affects teammates, so that's a little extra added utility.
All cats can get to over 75% crit chance with Bite alone, and a +1,2 crit multiplier is well worth 2 mod slots on a companion. Adarza just also has Cat's Eye, so you get to often double dip on the buffed crit damage with orange/red crits. Whether that's better than something like a Panzer is up to your frame/weapons, but it's a worthy contender now.
You want Dethcube to tag as many enemies as possible so he gets credit for Energy Generator, gas leaves a lingering AoE on enemies so if they run next to a guy your Helstrum didn't hit, that enemy is now damaged by Dethcube and contributes to Energy Generator stacks.
Edit: I also forgot to mention that Gas procs linger on the spot even after the afflicted enemy dies, so you get even more chances for free tags for our dethly cube to generate energy for you.
Dethcube is awesome for reliable energy generation with gas moded Helstrum, Adarza is great with Tenacious Bond and Bite, Nautilus is really good now with it's Cordon ability and Manifold Bond (and Helstrum to help apply statuses). I haven't touched any of the dogs (either biological or robotic) or Moas as their abilities were rather unimpressive even if they could stay alive forever. Here's hoping Phase 2 makes them better with it's companion ability rework. Oh, and good old Panzer is still really good, baseline 30sec revive while still spitting viral everywhere makes it remain a reliable option (it's also hella tanky now).
Mesa Prime is 100% worth it, one of the most effective and fun frames in the game (I'm totally not biased because Mesa is my favorite frame, not at all!)
This chapter was adorable. Look at these two dorks!
My favourite combo is the "Rolling Gunslinger" Mesa, taking the power of Mesa's Waltz to it's extreme. The required ingredients are 2 Parkour Velocity Archon Shards (or 1 Tauforged, which is what I prefer) and a mod you never see used, Amalgam Barrel Diffusion (put it on your secondary, not Regulators). With all things combined, Mesa turns from the turret frame she's known for into one of the most mobile killing machine frames in the game, rivalling even Titania. Once you get used to how much forward momentum her roll gives, you can traverse all but the most maze-like tilesets without ever turning Peacemaker off, shooting everything that moves all the way to extraction.
I love the friendship King and Saitama have, they are both the only people who truly understand one another.
This, this build is an absolute overkill supreme in terms of high-cost low-effect mods. Shield mods on companions? Why? A single Bond mod that speeds up revives in place of Pack Leader is all you need, if you really need to have your companion right now you can just revive them like before. And considering both Fetch and Animal Instinct remain active now even while they're down, there is no reason to hurry. Damage mods are still very much irrelevant, Bite has a use if you wanna run the one crit damage bond mod on cats to boost your weapons but that's about it.
So does Fireball and yet that one does no friendly fire damage. Either Ice Storm is bugged or it's as the other commenter pointed out, Guardian of Faith detected a hostile action and triggered an attack on all nearby hostiles (your party), which dealt enough damage to it to kill it.
