(Ward Importance)Do you think it's time tutorial got updated?

So currently I'm in b1 my first season being in bronze. I was silver last season and I don't claim to know much about in game mechanics and ratios/scaling haven't really played ranked much until this season and all that other stuff however something that bothered me and still bothers me being in bronze is that people don't seem to understand the importance of warding in bronze. I've noticed so far that me and my team rarely lose a ranked match when we have vision and everyone does their part to chip in warding however this is very rare and I find myself being the only one buying pinks or greens when I back or am doing really well in my lane. When I ask my team mates to get some vision up they either ignore me or tell me that I should ward ... which I already am and I explain to them that I'm slowing down my build because warding is solely left on me especially when the support doesn't take a sightstone or buy them and I also stress that it's not only the supports job to cover these bases. Vision allows for better ganks or avoidance of getting ganked, roaming opportunities and steals. In a way I think Riot kind of down ward importance with trinkets because people feel just upgrading your trinket is enough and even then not everyone upgrades their trinket. I feel that if riot stressed the importance of warding in the tutorial when people first start the game by the time they entered ranked play they won't have such an indifferent attitude towards it. Do you think riot should stress ward importance in the tutorial or nah?
