Literally all the issues this season can be tied down to 3 things.
IE change.
Stormrazor.
Skuttle change.
Simply lowering IE from 50% bonus damage to 30%, and leaving skuttle alone and we'd have had a reasonable season.
The issue with IE was IE + Zeal was too big of a power spike. Lowering the bonus damage would have fixed it without gutting ADC for half a season.
Stormrazor added burst in a season where burst was already too high.
The other jungle changes were in general OK but making skuttle such a high priority created gold funneling. How could they not see putting 2 objectives within a short hop of mid lane worth 2 siege minions each WHILE lowering jungle priority wasn't going to create this issue?
Seriously where do they hire these guys?
Oh wait.. they hire guys other companies let go...
