Show me the examples of small good deeds you do in World of Warcraft!
Here are a couple of mine:
A macro that whispers a compliment to another player about their cool transmog.
A macro that compliments the team to use at the end of BGs or dungeons.
Sometimes when I spot someone asking for guild signatures in chat, and offering gold, I create a temporary alt just to sign it for free
That’s cool. I always try to thank people for buffs, invites or pointing out a rare in general chat.
Helping someone who is getting eaten alive from what appear to have been an over pull.
Certainly giving out buffs is nice.
I think taking a moment to compliment a well done mog is a great thing as long as one knows when to stop talking to avoid becoming creepy.
When someone asks for help, I whisper to ask them if anyone has replied. If not help out if I can.
Every Christmas holiday in World of Warcraft, I’ll provide ports to the various cities throughout the game world for free. I also do a free giveaway in my guild for (1) free store mount each year! 
Before the reset , i depleted my +20 key to +15 , then offered +15 weekly for free at Stormwind , i took 4 players who never timed +10 keys
Being a tank when there is no else is around to help people.
I have letters from people who I randomly give gold (a few thousand usually) to, they love it.
Occasionally I give people free runs of old legacy content for free, no charge, just a courtesy…
If I see someone struggling in a fight, I will jump in.
If I see someone going for a resource node or quest item I am going for, I will let them grab it first.
I will pass out flasks to random people as I level up or using mats to clear out my bank (I had way too many flowers because I cannot pass one up)
i deny vote kicks especially if were almost done with the run/it’s a stupid reason. this happens a LOT in my dungeons idk why tbh.
i sign guild charters for free. all i ask is a simple “ty” sadly some people don’t say ty at all ontop of offering me gold via chat BUT they don’t even give me the gold. some do offer it after i sign but i decline. i don’t like signing peoples charters otherwise. find it very rude when people can’t even say ty but aye it is what it is i don’t say anything to them figure i best not expect anything in return to begin with.
i often help the opposite faction kill something off especially if it is killing them/they would of died. sometimes i find this annoying though. as i usually have WM on and when i help them out some of them attack and kill me. this is why now days i rarely do this anymore. if they do kill me i rez, find them and kill them.
when people mess up in raid i don’t immediately scream at them and call them names
usually
when I’m WM off and i see a hordie about to die to NPCs ill help them out… in WM on i kill the hordie and the Npcs …/shrug XD
when i see other alliance players about to die i help them all the time though
