4bot
The dragon change ruined bot lane. The only time there aren't four players at bot during a gank to make the game lose anything resembling fun for the opposing two is when Shen shows up from top and it's all 5.
Now it's way too much incentive to have 4 people go bot lane at any given time. Makes the game less fun for anyone who wants to ADC or Support, and lord knows how much we want the game to be less fun for supports.
Back when it was only gold, you could use it to make up for the enemy team's gold lead or make up lack of dragons by getting kills, but now if you want to play bot lane then you're just fucked. Doesn't matter how much you ward or back off, since they'll just get the gold from your deaths through minions and that tower instead, along with the dragon. Or you die and they get those anyway.
I've been playing for over 4 years, and bot lane was never so annoying to play--or have on your team-- before. Sure, they might get camped and you might get mid coming down ALONE to kill you, but when Dragon didn't give buffs that the opposing team can't possibly replicate through gameplay alone, you didn't have to worry about having that somewhat fair 3 v (2andtower) turned into a tower-negating 4v2.
