What makes a good support?

When can I say that a support player is good?

I've played with alot of support mains and auto-fills and most of them were really good I think.

Recently though I've started seeing two types of supports:

1. The engaging support: this support tends to poke and engage a lot putting a lot of pressure on the enemy adc. They help with securing kills and protecting the adc, essentially keeping me well and safe enough to be able to do my job as an adc without much danger.

2. The Safe support: this support stays under tower. They avoid engaging in any way possible, takes the least risks and do anything they possibly can to stay safe and alive, even if it means being passive. They usually have little experience of team fights and their role in it and may miss their abilities more than hit. The good thing they have is a near perfect kda as they're usually away from danger. The bad thing though is that in nearly every game they play, they're adc is doomed.

With the first type of supports, even if they're not very good, I win most of the time. With the second type, I'm almost always in danger of harass, can't farm because I'm under tower and getting kills requires too much effort.

At first I thought the first type are better supports than the second type so, I've tried telling the second type what to do, when to engage and where to ward. I don't want to sound toxic, but they almost never listen to me instead they go on to play the same way as if I'd never said anything. (They also tell me to stop talking to them and let them play how they want and just play, but that's beside the point) I figured maybe that's a new playstyle for supports, to be very safe.

If that is a playstyle and not bad supporting, can anyone tell me how to deal with that? like how to play and synergize with them and stuff like that. [vlad-salute]
