A very mathematical alternative to First Brick gold
(For the first 5-10 minutes of the game) In addition to granting global and local gold, destroying your first tower lowers the global and local gold the enemy team gains for destroying theirs (this effect lasts 1-5 minutes).
Bam. No early game tower trades and soloQ is affected only in niche scenarios. Certainly less affected than it is now. Unless I'm wrong and it's the additional gold, not the gold differential that killed lane swaps.
Edit: Damn, I'd've liked some constructive criticism before you downvoted my laneswap solution as you always do.
