Supports: Damned if They Do, Damned if They Don't
Since going main supp, I have experienced various players who say various things about what a supp should do. They all share one common theme: Blame the support. In many cases where a team member is losing their lane and they are called on it, and asked to be more passive so they don't feed, their instant response is to say the support is 0/X. This also occurs when your adc is everything but useful, be it their first time adc, trolling, or an idiot who pings for attack and doesn't follow up with the set up. They do this despite the support having half or more to do with the team kills (assists). An example would be you are 0/4/15 and your team kills are totaled to 26 in 30 minutes of the game. You have 0 kills therefore you cant play and are a loser in your teams eyes.
On the other hand you are a failure and a loser for getting kills. When you know your adc is too passive/noob/troll, and wont get the kill right in front of them, I tend to grab it so it would be worth it if they or myself died after they pinged to go in and then they have second thoughts. This is also when your jungle is too busy being scared or trying, and failing, to steal enemy jungles farm but is close by. You go ahead and take the kill that is trying to get away and get spammed about how bad you are for getting a kill that both the adc and the jungle wouldn't get. Then in cases of them just getting away outright and my cc ends up killing them. If I score the kill everyone is pissed that the support has kills and says that they need to learn how to supp despite none of them were even able to score the kill or dmg the enemy. If I let them get away then they are pissed at that as well.
Thus the title of this thread. If I score a kill because the rest of the team CANT as in not close enough, ran the other direction, died, are too stupid and focused the tank, not paying attention in general, the support is the noob for taking a kill. If I don't take the kill, I'm a noob for not having kills, not taking the kill despite them pinging that it is their kill and they end up getting killed saying, "hurr durr wtf why did you back off?" or some other general form of stupidity.
Anyways, what are your thoughts. I generally try not to take kills unless I absolutely have to, getting away, it is too close to call if my ally or enemy is going to get the kill first, or total accident. What are your thoughts?
combined with the new masteries make playing Full Ap mage supports in bot lane a serious thing that I do not think most people realize yet.

"Braum wtf man why did you take my kill noob?"
EVEN FUCKING WHEN I HAVE A CHARGE ON RELIC! "Braum stop hitting minions, you mess up my last hit fucking retard!"
No matter how horrible the adc is, when 3 more bitches come bot so its a 5v2 and the "carry" is gonna be blown the fuck up, jump in and shield and take 1,000dmg in 3 seconds. BUT, the adc stays to try to save tower and ends up dying. she tells me "WOW BRAUM YOU SUCK %%%%S!"
