I'm a support main, and also in bronze. My csing is too bad for this! I tried playing a different role but twice now when it looked like we were gonna win so I started farming the difference, the enemy surrendered before I made it :c
Pandemic Punch6 votesPlay ARURF and get Krugs and raptors when you get the chance
Shuyin1782 votesThat's when you play split-push Sivir top lane, you'll reach 100 CS every time.
Eleana2 votesJust play Urf, pretty easy to get tons of CS
ValyrianBlade2 votesAs others have commented, play urf.
It's not easy there in my opinion, but then again I'm often focusing on kills and not cs in urf. Which is the mentality of most, so you should be able to farm up a storm if you look for it. Get krugs and raptors whenever you can (pretty much any champion can kill camps in urf taking minimal damage after a few levels). Towards the end farm the difference if you have to - people don't surrender in urf and I've successfully asked my allies to wait a minute before ending so i could get that last 8cs or whatever.
MoiMori1 votesbot games are good for this. Just call solo top and play 
and buy 
and you'll be taking down a whole wave in about two shots. Also the Krugs in the jungle count as 10 minions and the birds as 9
