I play Supp/Top end of the spectrum and way different champion styles, but if you want to stay in the same lane all the power to you. As for "smart idea" just think of support as an amplifier to an guitar. If the guitar is being played well, kept in good shape, and has good tunes the amp (supp) will make it that much louder and so on. Now, if the guitar in question is broken, missing strings, and begging to be salvaged then ...........yea. You get the point. Depending on your Elo, support is strong or very limited. If your adc is overly passive, no matter what play you setup it will be useless. Since you play adc you should know how the average adc will think and work well in terms of synergy.
Supports that are friendly to newer supports:
E, land on them, Q for stun, W to help you not die. Big ass stun/slow circle as an ult. Very cookie cutter tank supp.
Passive aura that gives armor, a heal, and a point click stun. Ult is going man mode.
A shield that also gives AD, a point click slow, and tornado skillshot that can knock up, and a huge peel for ult
You heal, you can silence with an aoe, you poke a bit, then a karthus ult that heals your team instead of damage.
Once you get a feel for supporting, try the more common "play maker" supports that can set up ganks and kills very easily but are mechanically more difficult.
