The recent flame and frost living story has been a bit underwhelming in terms of gear. Sentinel armor? I don’t really think so. (Fused skins are great if you can get one though)
How about some gear that is actually good? I’d suggest a new range of sigils that extend weapon range by 5, 10 or 15%, or increase AoE by 5, 10 or 15%. Or a rune set that has increased precision and weapon range as bonuses.
Not OP, because you’d sacrifice the opportunity to use the sigil slot for something else. Might make for some interesting builds, too.
