You don't have to worry about CS, and most supports are not mechanically challenging to play.
So they basically just put wards down and basically climb to Grandmaster over night?
Serious question because I'm really trying to hit gold this season and want every edge I can get.
here
play janna
she will boost you one standard deviation if you put time into her.
no it doesn't matter what season it is, this is janna, she is spectacular every season.
enjoy.
Easiest/Hardest role differs on each and every player. it depends on what playstyle resonates with you.
Example: to ME, ADC is the hardest role. I can lane phase fine with it, but i don't really know when to leave lane, i dont know how to keep farming as lane phase ends, i dont know how to properly position for late game teamfights, and im not well adjusted to playing champions whos primary damage is left clicks.
Support is the hardest role in low elo because you have less impact on objectives than any other role and, I mean, who the fuck wants to support a Bronze ADC?
Yeah it's the easiest. You can climb higher than your skill level with support.
And before anyone(support mains) tells me otherwise, take any d1 support and d1 mid/adc/jg. see what winrate the d1 support can have if they off role mid for 20 games (on same account obviously) and have the midlaner/adc/jg do the opposite.
Support is just the easiest role, and I am a support main, guess why... cause it's easy.
ANY player that is new to the game and plays with their friends is sent to support....why is that I wonder... I started in season 2 and all my friends were plat-diamond (1800-2100 elo back then) we played normals 5man, guess what was the only role I actually did really well on, meanwhile I fed all the other roles.
If you want to climb as a support there is one downside. You have to actually talk to your team. Whether it be through pings or more likely through 30 minute long morale boosting diatribes typed in a 15 minute long game to get people to stop crying, pick up their shit and get moving and actually try to win again. The reason I quit league for 5 years is because I used to play support in S2. The first game I won as a support and actually felt like I mattered not only did I play my fucking heart out I also spent the entire game typing in chat telling every single member of my team exactly how to play their role, their champ, the objectives, the teamfight strats, boosting their morale when they fail and giving them dog owner pats on the head when they succeed.
it's goddamn exhausting.
Or y'know, you could just play 
and give the enemy team cancer due to dealing more damage than her ADC and somehow still having enough utility in her kit to be called a "support". Senna can go die in nerf hell what a cancerous champion.
If you know how to be aggressive and roam, yeah sure, its easy. If you're not warding, then you shouldn't be a support. Its the reason why I play support because I don't like playing in a dark map. I want to actually impact lanes, ward objectives, etc. Just be an active support and get double control wards for every back. Also believe it or not, your team depends on the support for quite a lot. Don't let them down. Do more than just be a ward/heal bot, you can do so much more. Actually carry them.
The best advice I can give ya is don't die if your going for this route.
Most supports can be targeted very easily and killed before the adc can react. If you get a slight advantage you can force the support out of lane making them free gold mid game... Silver elo rarly has godlike duo so if you pick on the support sadly ppl will flame them and they might make more mistakes laveing the adc open for anything. If the adc is an apc or bruiser you just need too force one of them out staggering their backs.
If your use too a certain champ or lane I would suggest you change up your style in that area.
I'd say support is arguably the second hardest role... right behind Jungle myself. At least the hardest to carry with.
If your ADC sucks you have to be twice as good to make up for it. Also CS'ing isn't hard to begin with outside of pre-first back so I don't know if that much matters. The moment you buy 
or 
CS'ing is pretty braindead.
