Adding a bit of an anecdote, I’m not good at games but when someone (be it friend or foe) is leagues worse than me I give them advice

For example I’ve been getting back into planetside and this level 7 was trying to kill me as an infantry unit with a rocket launcher (anti tank weapon, can’t one shot infantry) so even with my crappy aim I dispatch him without so much as a nick to my shields. So I send him a direct message that the rocket launcher is for tanks and he should use his LMG for infantry battle

Basically help your newbies
