I'm Never Buying Movement Items Again
To get it out of the way, yes, this is an anecdotal experience, but by god it was such a drastic change for me that I need to talk about it.
I'd mainly been following popular builds, and pretty much all of them tell you to buy boots and stamina and so forth.
Except, no matter how hard I tried, I'd just get caught anyways. Even with superior stamina and long jumping all over the place, enemy team caught up to me like it was nothing.
I decided to stop buying those items all together and just spend them on damage/shields and OH MY GOD. Suddenly I'm winning more often than not, or at the very least trading well.
These movements items just don't do enough to be worth the item slots when there's 10 different items that slow you down, ontop of whatever CC the enemy team might have.
