Yesterday's game was nice and intense, but at some point my fellow players disappointed me, heavily.
We're not allowed to say technical things about the game.
Basically we had this dragon that was very much damaged, prone and slowed. We also were very low in our resources, especially hit points and we didn't have the opportunity to take a short rest before the dragon fight.
The monk knocked the dragon prone and said "Attack him with your melee weapons". Then I (bard) slowed the dragon, I read the spell effect aloud (that's allowed) and my character translated it as "Just hit and go back, the dragon is too slow to surprise you with a hit".
Then the ranger, level 7, 15 feet from the dragon, takes his bow and attacks the dragon, only once, and misses, then says "I end my turn". The DM, who never asks this, asked "Are you sure?". The player answered "yes". I facepalmed. The DM says "you could have multiattacked and fetched an advantage by going melee". The paladin makes the random note that "multiattack is a very nice feature".
The very next turn is the paladin's turn, level 6, 20 feet from the dragon, goes in melee and attacks with their weapon, and hits. But no smite. Then moves back and says "I end my turn". I facepalmed again. The DM repeated his question, "are you sure?", which he never ever asked before the previous turn! The paladin's player said "yes". The DM reminds the player that he said "multiattack is a very nice feature so why didn't you use it?" - The paladin player says that his character is badly wounded and that it makes sense that he's not giving all he can. I facepalmed again.
The next turn, the dragon escaped. We later learned that it had 20 HP left, basically we were 1-2 hits away from killing it.
Now the ranger player has a difficulty retaining all his character's capabilities, and the paladin player is customary of random handling of their character and finding weird excuses to explain it when we show it to him.
How can I explain to them that they should pay attention to what each other character say, and that at this point my fun is greatly reduced because we try to make it easy for them to understand the situation and they just don't pay attention, and do random, unthought actions instead?

- While I personnally want to play optimally, I accept that everybody doesn't play like that and has different playstyle. I don't want to play a tactical game, even though between the DM, the monk and myself, it's clear that we're the three trying to optimize our moves. However, I don't want everybody to play optimally, but also, I don't think it's wise to play against a dragon (our first in this campaign) just like we're level 1 players.
- This campaign started in January 2019 (so is running for 2.5 years), with one session every 4 weeks, plus a few extras during last year's confinment. Both the ranger and the paladin started the campaign, I joined in November 2019. We passed level 5 last year (that's the level where both players got multiattack). The ranger plays 3 TTRPG each month but I believe his introduction to TTRPG was with our campaign. The paladin plays several TTRPG each month as well and has been playing for a long time before our campaign started.
- I don't believe the paladin made their move intentionnally, but I may be wrong. As mentioned, the paladin has a background of trying to roleplay mistakes as if it was intended. I believe this is what happened in this scenario.
