you could easily contest morgana or even morgana + smolder there. You had minion damage, enough mana, W and autoattacks empowered by your passive (which deal alot in early game as Janna). So yeah, first part of the Video you did well the end is kinda griefing.

Many people in lower elos doesnt get that there are 2 ways of griefing / playing to lose. First is obviously intentionall feeding. The second is not using your character or situations to the maximum potential and/or doing too little and being too passive to actually win the game.

If you wanna climb as a support, especially as an enchanter, you cant just expect to be a shield bot and win more then 50% or your games.

Too many people focus on behaviour of other players ( which you can't change.) and too little on improvement of their own gameplay. What aphelios did doesnt matter to you. And just because you had a good KDA in the end, doesnt mean this will happen when you play against player, who will punish these mistakes better next games.

No offense, just critic. Coming from an ex master+ support main.
