I am a support main. I have played support since season 3. And some of the observations I made are as follows
-Supports arent Kill focused: I can stun down the whole team with cc, I can go overboard with assists. But I have been told How much of a trash/garbage player I am, not because of my deaths if I were to go 0/5/26. But Because I DONT HAVE KILLS. Support is supposed to be a more utility based role. Stunning down enemies with cc, healing allies, placing wards fr vision. But apparently because the support cant Penta every 2 minutes, the support is trash. All thier assists? they mean shit all. You can set up an easy penta and whoever gets it will be overhwhelmed with "GJ, Awesome man, way to go" etc. But if support dies in the process, instantly they are labeled a feeder. And if you set up a kill, dont expect to actually get any aknowledgement for your contributions to the team.
-Supports arent actually part of the team: The team treats support like a "Lane-slave". You are just there to shut up and ward. You will be called upon to heal, and sometimes throw yourself at the enemy for the sake of a dive. But Any observations you make to the team, any suggestions are completely ignored. Why? Because you are not actually part of the team (and I have been told "Stfu ur 0/3" again tying into the previous point about not being focused on kills)
-Supports arent allowed kills/cs, are expected to keep the team alive on scraps: Yep, there is NO RULE that says a Support cannot take kills or cs (though I try not to be a d*ck about it). But the moment support even takes ONE minion, everyone loses thier minds.
Had an adc who dived and got herself killed. When I got into lane I took a minion wave or two. And Suddenly see "OMG STOP TAKING MY CS" coming from my Adc who was still waiting in spawn. Even if no one is there, the idea of support taking even a SINGLE minion or kill is treated like the same as trolling (So The team doesnt want support taking kills or cs, But will use the support's lack of kills/cs to completely invalidate anything they say. Seems legit)
- When all else fails, Blame support: yep. Doesnt matter how good you play, how hard you try. The minute the match goes south, the team will get to use the support as a disposeable "get out of responsibility free" card. As soon as the match looks like a loss, Either the support or jungle will be used as a scapegoat/sacrifice so that everyone else on the team doesnt have to admit they contributed to the loss. "We would have won if not for trash support" And In other cases the support is used as an actual sacrifice. Need to get away? just run towards your slower moving support, dump the enemies on them and continue to run away. Then after your support is dead, turn around and blame them for getting killed and talk about how "We would have won but trash support fed" or something like that.
Supports in general are treated as disposeable, Not even worthy of basic respect. No matter how good they ward? its not good enough because "warding is supports job" so that means no one else needs to buy ANY wards. right?. Doesnt matter how good your cc is, if the enemy escapes its because the support sucks, not that the adc ran away from a last hit. When any teammate dies, its the supports fault for being a trash healer, it has nothing to do with the support having to CHASE THE LAST HIT ALLY across the ENTIRE MATCH (Yeah, pro-tip. If you are last hit...DONT RUN AWAY FROM YOUR SUPPORT, MOVE TOWARDS THEM. Supports cant heal you from across the map...unless soraka)
Ruin-it (Riot) thinks no one wants to play support because of items and experience. No, No one wants to play support because They are treated worse than the dirt on the bottom of a noxian's boot! These are just a few examples of How bad it is playing support.
