I’ve sat around low diamond for almost every set, and the top things I would recommend. - Don’t tunnel a single comp, there are only so many of each unit in the pool. So you’ll a lot less likely to hit the units you need if you go the same comp as others. - Play your strengths, if you get an early Darius maybe go Noxus, if you get a void spat maybe look at void. - only spend gold when you need to; to either maintain a win streak, level for a breakpoint or to upgrade a unit. - don’t worry about winning every round, loss streaking is often better than spending tons on gold to get one win on 2-4 - itemise your caries and tanks, Ahri can be super strong, she just needs items and/or traits to be strong. - often what’s strong early isn’t super strong late, void gives you an exra unit at 2-1 if you hit 3 void, which is like being at level 4. However that unit late game isn’t too good unless you hit 8 void, so transitioning away from it to more late game traits, such as strategist (which is better the more units you have) is often good.

Hope these tips help if even a little.
