Seriously, and if you upgrade the blue trinket, it's also a WARD with huuuuuge placement range - a visible ward, yes, but that's all it takes to spot out someone approaching. People - and that includes junglers, because I keep seeing people in just about every role forgetting this - need to be upgrading their trinkets omg! These trinket upgrades have gotten really good, especially the green/yellow one! (Unless you have a red so that you don't have to smite raptors and the enemy team has no stealth, then it's ok to prioritize other things, but even then... it is pretty cheap lol.)
The stereotypical adc main (every once in awhile you meet a nice, knowledgeable one and praise the matchmaking gods) is so toxic for these reasons. "My farming is what will carry the game," they say, when you need help on an objective, so they let you lose objectives because their farm is OMG TOO IMPORTANT, but then, when you don't get dragon because you don't have the damage to take it on your own before someone spots you out attempting it and you're low from no help, suddenly "I can't carry the ****ing game without you getting objectives when they have all these dragon bonuses because you couldn't take any, scrub!" So, your farm is going to carry the game and therefore you can't help with objectives, but without me getting objectives you can't.... carry the game... that you said you would be doing with the farm...
