It's not the incompetence.
It's the change to the bounty system which now only gives the primary killer gold unless the bounty is over 3+ kills.
Silver players have always more or less had the same early game they have right now. But the Bounty system change funnels all the kill gold into one champion, and even if you do shut him down, the team often doesn't get rewarded for it. The result is..... a reduced capacity to recover.
It's also the fact there really is no counter for
, other than shutting a game down early, which is really really not where the game lengths in Silver tend to be. Even smurfing, Silver games often run 35-40 minutes, which gets IE into play, and unlike the old version, part of the damage is completely unmitigateable. And when it's coupled with
, there is no getting away.
In other words, in low elos, Stormrazor + IE have become anti smurf mechanics, as well as anti low elo mechanics (because even as a smurf, you're forced to focus one predictable build: either AD or AP meta.... because delving into tank / damage mitigation is more or less useless).
I used to be able to split push to change the tide of low elo games, but now..... teams in Silver literally WANT to die. It seems like every time an Objective is about to be up: run down mid and die in a 3v5 push. And, they die so frequently, that split pushing is next to impossible late game. By the time you reach a lane, set a Zzott's, etc, 3-4 of their team have already risen, if they died at all.
About the only time I can actually split push is at the exact moment my team is suiciding over an objective.
