questions about armor bonus and insignias

I have got a huge gap in my gw play and gw game itself has been changed alot
So I dont know if there is any armor bonus or insignias still work universal /globally like the old mesmer armor bonus.
could anyone give me an answer and explanation to this question, thank you in advance.

Insignias are only for the Nightfall armor. They have replaced the innate mods on armors there. So, after you buy your armor (at a reduced cost now) you then should pick out some insignias for your armor. Generally, the bonuses are locational if they add armor or reduce damage. Otherwise, they should be global.

No. The Knights for warrior and mesmer sets that were global was fixed a few months ago to be local to that armor piece only.

Thank you very much.
