Call of the brotherhood on deadeye ranger

Hey guys. Playing my 2nd character for few days now and I decided to try Call of the Brotherhood on my deadeye. Currently I'm leveling 40 playing lightning. Is this ring something I should stick to while campaigning or is it not worth it? I have a feeling it saves me so many times by freezing enemies but what I'm wondering is how it actually works with Shock and Chain Lightning? Do I keep all of my bonuses from lightning damage and passives but just freeze on top of it (that would be great!) or do I lose lightning bonuses as my damage is now Cold damage? Appreciate any tips and input on this as I'm not very active nor I had too much time to theory craft and explore how it all works. 🙏

I was playing gemling LA and happened to have this drop for me around lvl 50. Here are my quick notes on interactions as I leveled with it from there on to 88ish.
Abandon lightning% bonuses, covet cold% instead. Because conversion is 100%, you'll never inflict shock via damage so cast on shock is dead. Polcirkeln is probably the other ring you want given that you freeze everything in hopefully a handful of shots. Chilled ground effects help keep up against freeze bonuses from polcirkeln.
Just to add something, dunno if it'll help, but if this ring works anything like the original sin ring (converts 100% elemental damage into chaos), it will only affect damage type added by items, not damage type added on the passive tree (i.e. passive node or time-lost diamond) or skill support gems.
