Bloodied is something I kept, if only to inform players. I usually don't mention how many HP an enemy has, but I concede that character, in-universe, have a lot more information on whether a foe "looks wounded" or not. So I freely inform then when creature are at half-HP. Informing them with a spore attack would improve the situation ;-)
I used bloodied to inform players as well, but it doesn't take much for the them to figure out the monster's hp.
When you say bloodied, all the players have to is add up the damage they inflicted so far, and multiply by 2.
