People should learn the difference between 'New Meta' and straight up trolling
Loads of the Pros intentionally take sub optimal picks/comps for early LCS matches because they want to display cool new ideas, show off and because they know they will win if the enemy team has a sufficiently lower skill level and that's fine.
Don't do it in ranked.
It's not the new meta, because they know it is less good than standard in-meta pics, they are doing it because they know they will win. You are a Bronze/Silver scrublord fighting against other players of a similar skill level, if you do that, you are being selfish and intentionally undermining your team.
An example of New Meta is Graves top or Brand support, these champs are actually good at those roles right now, either because of their stats or their synergy with the new masteries - please do pick these if you are on my team. Do not, under any circumstances pick a bruiser as 'support', not take a support item and then claim it's ok because it worked in LCS, it's not the new meta, it's not a hyper-aggressive kill lane, you're a dick.
