Here's some awesome gifs courtesy of Roy Blakely's awesome noob guide on Polygon:
Yeah, let's show a stamina bar to show the monster is tired instead of this
G. Macc getting his tail obliterated.
The actual battle damage isn't prominent on the gif, but the spikes shatter and he loses his ability to balance on it, which affects his ability to fight!
You need to see a HEALTH bar rather than all these genius implementations of showing a monster visibly getting weaker over the course of the fight??? And this shit isn't exclusive to the Great Maccao, all of DOZENS of monsters are designed brilliantly to have their own signs of weakness. Exhaust Rathalos and his fierce firebreath sputters out into a hilarious puff of smoke. Gut off Yian Garuga's tail and his once extremely fast acting and deadly poison does a pathetic trickle of damage before wearing off.
I'll never argue that the MH series is short on quality of life shit that would make it much more engaging for a new player, but arguing for a LIFE BAR diminishes the insane amount of work that went into making every monster feel unique and amazing to fight.
