Since botlane towers are weaker?
Would it not make sense to put a tank/bruiser/mage down bot and then a support to stop bot tower from being destroyed so fast? Then you could move a high mobility ADC such as
or
to the top lane and they would have an easy pickings for a traditional top laner as they can outrange them and kite.
Until at least Riot buffs bottom towers to make them stronger and it may stop this "4-man bot lane gangbang" meta that is becoming so boring.
