Bearing in mind that I'm not the best hunter in the world, it was a moment of personal triumph in MH4 when I walked into a room of players preparing to take on Gogmazias for the first time, in full Gog armour, and they treated me like I was some kind of superhero who could complete it for them singlehanded. I just imagined my hunter mumbling 'er, I've had a lot of help...' to no avail!
I always tap 'nice work!' when I see good play like driving off creatures with dung bombs, consistently good use of flash/sonic bombs and traps, successful mounts of raging monsters, players stopping a quest from failing with heals etc. It's nice to be recognised now and then.
I also had someone compliment me on bugging out with a farcaster rather than cart once, which was very polite, considering how badly I'd fought to be in such a bad situation where I had to teleport out rather than flee to the next area! It really is my absolute last resort, usually I only use it for delivering subquest items.
