Why is everybody surprised at what's happening?
It couldn't be more evident that the pre-season would be a clusterfuck (it's almost always like that). This game is being transformed into a fast paced team deathmatch. Last season was already a balancing nightmare and it's probably going to be even worse this season. We're at the point where we have so many champions that you change a single stat on an item or a keystone/rune and it shifts the entire balance in favor of other champs that will become OP. There's no way around it. Now with all the base stats changed and the new runes, it's going to be even harder.
They never said anything about changing weak ass towers that get annihilated easily so say hello to more snowbally games (most of the community agrees this is bad). They should rename the game to: League of Action Packed Super Killz. The dragon changes were good, the herald changes were good and surprisingly the plants were also a cool thing but I hope they know where they are going with this.
It seems like Riot is trying so hard to make sure this game stays alive year after year that they forgot what made it the most successful MOBA to begin with.
Change can be good but too much isn't.
