I agree on adding the TNT, even tho I don't do PVP these days.. :L
Also, when you die from TNT, it acts like any other explosion (Creeper as an example) so this would, if it isn't tweaked in some way, make you lose your items, therefor as you said Anime, it might need to be changed up a bit :p
My ideas is:
- "..." Died From Stepping On A Land Mine
- "..." Died From A Blow
- "..." Died From A Explosion
- "..." Got Nailed By A TNT Explosion
Random ideas, but at least something to work with :p
