preflop raising, epecially opening the pot shouldnt need to be so large, afterall we dont suck postflop to pay every piece of crap off that gets lucky do we?

Bet size should be not be a consideration, you should just c-bet a standard amount every time. The skill should come from checking when youre expected to bet and betting when you should probably check at times or take a free card. Amounts are pointless particularly on the flop. If someone is calling a half pot c-bet on a board you pretty obviously hit hard then theyll call a 3/4 pot bet as well.
