The tip maybe is something the player is already aware of and that's the zetaest time he is already working to get better.

For example, hit positionals. Hit positionals aren't something you can do out of blue. You actually need to adjust your way of playing the game, adjust your muscle memory and develop some better sense of positioning to be able to position your character well to do maximum damage. And that is easier said than done. Because to actually do that, you have to invest time (I'm speaking about entire days or even months), effort (because those things requires effort) and patience (since that person will fail to do that. A LOT).

And let's say that monk enters on a duty where he fails at hit positioning or just plays the way he is used to, to not risk dying or dropping too much his DPS while trying to hit positionals. That monk knows that DPS without positionals are his best ATM. And then some player notice that and gives him a tip, saying that he should hit positionals. No futher explanation about an easier way to do that, just "you should hit positionals". Generic, like that. AND that player who gave the tip just expect that the tipped player would magically begins to hit positionals right away just because he gave the tip.

How that tip is not annoying?

Maybe is would be better if the community is more open for people asking. Maybe an actually helpful NN - that rather than yet another hunt LS is an actually a place where sprouts can ask freely and receive actual, contextualizated tips - would be better than give and receive random generic tips while the duty is happening.
