finally caught up with the juicy drama. as princess zkylana, lewd arbiter of lolgaf, i gotta say that i'll stay out of it and ppl should just try to be nice to each other :>
sometimes people need to vent, sometimes they need legitimate advice, sometimes the advice you can give them isn't what they want to hear, etc. try and be nice.
i think "learn to carry" is not the easiest concept to explain, either. like, people have so different ideas of what "winning lane" means, but ultimately whatever you did in lane doesn't mean anything unless you affect the people outside of your lane and that's where carrying comes from. if you won lane and are now roaming bot and getting ur team a double kill and a turret, that's great, you're carrying. you don't have to get the two kills yourself and do mlg plays, just extend your advantage to the rest of ur team. if you won lane and are now a splitpush threat that is gonna chip away at turrets whenever they have the chance, that's great, you're carrying, but if the only thing you're doing is delivering waves to the top laner that's behind then you're not really doing anything. and if you won lane so hard that the other laner is super starved and needs to steal jungle creeps or needs jungle assist to reset the wave cos you froze it and they're absolutely fucked then yeah, you're carrying. similarly with objective control, teamfighting, etc.
and ultimately you need to do the type of carrying your team needs, not the carrying you want. the team doesn't have to adjust to you, you have to adjust to them, so it's a lot about identifying what your team needs you to do. i'm not of the 1v9 mentality, but you just have to meaningfuly contribute, not just be ahead of your lane.
a lot comes from general game knowledge that tells you when to make objective calls and how to play matchups and being really comfortable taking calculated risks which is probably the weakness most players share, not knowing when to take advantage of cooldowns and power spikes from items and levels.
