I agree on Quick Respawn, at least in ranked. It's one of my favorite abilities. Special Charge Up I'd probably agree with as well, although Tenacity I'm not a huge fan of and I definitely don't agree with Recon.There are only a few abilities that in my opinion can definitely be effective for any weapon on any game mode:
Special Charge Up
Quick Respawn
Tenacity
Recon
In my opinion I personally this it is a great ability for rainmaker and splat zones, and even more so if you play charger cause you can see when you respawn/ retreat their movement and warn your team with "booyah" spamming or set yourself up in the perfect sniper nest for their attacks. plus this is great forI agree on Quick Respawn, at least in ranked.

I just don't think Recon is that useful, considering it only works on the spawn point. Except for the moment you respawn, there's never a moment in the game you should be standing on the spawn point. While it can be useful for identifying allies to whom it's safe to jump, it's not much use for anything else. Combat is so fast-paced in this game that by the time you make your way from the spawn point back into the action, everyone's positions have probably changed significantly. I don't think Recon is worth a whole main gear slot.
Personally, I would swap Tenacity and Recon in your list for Cold-Blooded and Swim Speed Up. While it's true that there are times where Cold-Blooded will be useless if no opponent has Echolocator or Point Sensors, both of those are common enough that it's worth using I think. As for Swim Speed Up, I include it because fast movement is so important in this game and every single weapon benefits from it in some way.
As a charger, I tend to move a whole bunch, and I find staying at one place is very ineffective as a whole. The main abilities I use as charger areThere are only a few abilities that in my opinion can definitely be effective for any weapon on any game mode:

Chargers:
Most of the time when you're using a charger, you'll probably be staying back a little and not moving as much. That is why I don't think movement-related abilities are really effective for chargers (disregarding the squiffer and bamboozler). Some other abilities are definitely viable though depending on your play style.
This is just a quick list, and obviously everyone plays differently so most ability setups will be completely unique. But let me know if you agree or disagree with any of my thoughts!
