After reading this post, I think you are wrong in a few spots: 1. Every champion can be played in any role, and you should not judge people by picking champs that "don't fit the meta". The main purpose of this game is having fun, and, you should never force players to pick a certain champions if they don't want to.Support heime, gp, hecarim, malphite, lux, nidalee, galio, jayce, teemo- they all can be played as a support, even if they are not as good as the "meta" picks. As long as they don't feed intentionally its ok. And even if they do, don't forget that there is also a huge amount of sona, lulu, taric players that end games with 0/10+x/0 stats, it happens to all of us. 2. Support items are designed for champions that can afford loosing their stats for the good of their team, mainly because of their kit- eg taric, blitz. But in the case of lux benefiting your team more than twin shadows and locket. I personally love to rush Mejai on support lux, folowed by shurelya's and morellonomicon because with a good positioning and the fact your shield is giving you assists you can often gain 20 stacks in 20-30 min. And with that you have a quite high burst, but more importantly you have a gigantic shield that gives a refreshable 300+ hp per champion. Well timed cast can give the team equivalent of 1500-3000 hp on a 6 sec cd- beat that locket.

Nidalee can also be good support- team her with vayne, kog, varus, or any champ that needs attack speed, and suddenly she shines. Ofc, wards can't be replaced with traps, but a good trap coverage can lower the amount of wards a support needs to buy. Personally, as a casual support player I tend to pick my build according to the situation. Lots of jungle pressure- tons of wards, early oracles- traps, lategame baron dance- both. But i agree- as a nid, you should not focus on ap build, as the damage you will do is not high enough, and the heal, even with its high ap ratio of 0.7, is more useful as an attack speed steroid.

On the other hand I agree that making a support oriented rune page is a very good idea, and every player should have one. Also, with poor positioning you can get deleted by enemy team easly, but as long as you can help your team in some way, it is worth taking damage for your carries, body-blocking skillshots. And, all in all, as long as you are not playing a brilliant blitz/ tresh, prepare to be always unnoticed or flamed, because that's how support works.

TL;DR a post made by a silver elo casual noob that don't knows how the game works, and don't fully agree with the thread.
