TL;DR: the bottom carry(and jungler) have too much weight in 5v5 matches and my suggestion to fix that would be to make mid-lane harder to push. My long post just explains why I think this
This meta is so annoying and ridiculous. The tank-top push-bottom metas puts a lot of faith into the bottom carry. They’re essential they backbone of the team while top tank is essentially useless if the enemy team bottom pushes harder and stronger. Right now usually the jungler will excessively gank the bottom lane and keep the enemy top carry from farming as best as possible this is why majority of players choose a tank to top because they survive better and don’t need an expensive build(they won’t be able to afford an expensive build when they’re farm is gone). Usually the bottom carry is the one who has to carry the team now and everyone else is dependent on them because if the enemy bottom pushes harder and farms better they’re simultaneously depriving the top tank of farm and gaining more farm so now you have a bottom carry who is weaker then the enemy bottom, a top tank who is weaker then the enemy top, and generally the jungler will follow after the bottom carry so they become weaker or stronger dependent on them. It’s not a matter if the top tank does well or not it’s a matter of how well the bottom does. This is a meta that gives too much of the matches outcome to one teammate in a team with 5 players.
This type of meta was ok for 3v3 because you only had one lane and three players so it made sense that someone was gonna be the more prominent carry but in 3v3 it took the effort of both the jungler and support to make the carry strong so even if the carry had the most damage and money the jungler and support still matter; and this was vice-versa even when we had jungle carry metas because the lane was still important no matter the meta, in 3v3 everyone always matter even if it was carry focus meta.
In this 5v5 meta it doesn’t matter how well the Tank, mid-carry, and support did in their lanes and I don’t mean how well they farm but I mean how well they farmed and survived based on the amount of lane pressure they received from the enemies because the tank top position can only do so well when they have two dps constantly harassing them. If the enemy team has a bottom carry who farmed better they’re stronger than your bottom carry and the enemy bottom carry can only get stronger if they put enough pressure on the Ally tank top so you always have the ally tank top being weaker while the enemy bottom carry and jungler stronger therefore your bottom carry and jungler are weaker. I know this sounds confusing but these things are all dependent on one another and are in most cases have the exact same outcome.
My suggestion to this would be to make the midlane harder to push. As of now the midlane is too easy to push so it requires that the support stick with the mid-carry majority of the farming stage because losing the lane would be to big of a punishment. If the midlane was harder to push this would an insensitive for the support to go top more and help out the top tank and maybe we as players could have more options for the top lane seeing as the lane wouldn’t just be an easy farming lane for the bottom lane anymore. This is just my thoughts on the 5v5 meta, maybe I’m wrong but I really dislike this meta because it puts so much of the matches outcome on one(or two if you count jungler) players hands and makes me feel useless at times when I play a position that isn’t bottom(or jungler). I think every role should have a more important part and it would not cause as many players to tilt since they don’t feel like they’re losing because of someone else at times.
