Don't AFK before the first wave.

Not at base, not in your jungle. It's dumb and lazy. I know when we all started this game in Wood V, the first 1:30 of the game was basically a bathroom break or emote spam session, but when you rank up a bit the game starts right as you spawn. I've only been Gold IV at the highest, and probably 1/5 games there's some kind of skirmish before the first wave, potentially costing your team summoners or kills if you're not around for it. This puts your team behind from the beginning, and is a huge hit to morale. You are not safe in your jungle no matter what the team comps are. EVERY invade is dangerous if you're unprepared.

If anything, you should encourage your team to invade every game in the hopes there's someone dumb and lazy on the other team.

That is all.
