Tower gold

Some times more often then not I find when ahead early game its hard for teams to keep their momentum going. Adding a gold raise and bonus 1st tower gold could add more strat and punishment to bad plays. You always see a top laner getting kills and towers I think making deaths more costly over first blood bonus and then a 1st tower bonus making every death even more costly. Let me know some of your opinions on this love to hear some pros and cons.
