I have multiple suggestions that I'd like to go over.
First, I think the thunder idea is great but in my opinion it would be even better if there was two different sounds between someone getting killed normally and someone getting one shot, for example the thunder sound could stay for only one shots and for normal kills there could be some other easily distinguishable sound that everyone is familiar with, because in the past years I remember how exciting it was to hear that thunder sound in game when someone got one shot.
Second, I'd like to suggest to make the color of the chat while being in game some other color than gray because it was really difficult to read chat, especially on Jurassic Lights Out where most of the map is white snow.
Third, the pvp today felt... weird. Even though we were in 1.8 it still felt like it was 1.13, it felt clunky. I don't know if that was an issue just with me or with everyone but I feel like something can be done to fix it
And lastly I'd like to suggest to change the loot inside chests, I think it would be a really good addition to have extras such as cob webs, tnt, rods, etc. In addition I think it's a bit too overpowered to have diamond weapons spawning in chests, for example in today's beta I got a diamond axe from a golden chest in spawn at the beginning of the game... instead of that I think diamonds and sticks should spawn in chests so that you can craft diamond weapons. Another way that it could be done is to keep the diamond weapons but make them extremely rare because currently it seems like they are pretty common, in deathmatch there was always someone with a diamond weapon. Lastly I think the leather armor spawn rate should be lowered or changed because I got tons of leather armor just from spawn. And also chain armor could be added for more diversity. Also more foods could be added the the chests such as cake, everyone loves cake c:
