As you may have noticed there are a bunch of characters that I haven't normally played, that are actually the characters I should be playing. All my favourite characters are F tier
Lol, "F tier". Dude, the tiers are for tournament-style gameplay. You can't compare it to solo queuing, especially not at a lower level. Characters are a higher tier purely because they get picked more often, and this could be for a RANGE of reasons. Pro players are really skilled so obviously they would pick characters that fit their skill more. The compositions for 6-man pre-made tournament teams will also look very different from that of solo queuing low-level teams. And some characters are just super trendy because of recent findings, like how Ana x Reaper was all the rage during the latest tournament. You're not going to find that Ana x Reaper co-ordination in a low-level team though.
Seriously dude. Stop looking at tiers. You're completely missing the point. You need to look at what characters work for you, what characters work for your current goal and what characters are a good counter-pick in your current situation.
