Yesterday I nearly felt guilty about it:
I was going to play Xerath because I had my share of Aurelion Sol and botlane games and I hoped I might aswell unlock the chest with him (got like 5-6 keys). That until I saw the enemy pikcing Kassadin. At that point I told myself if I really wanted to give him the upper hand and have a stressful (and with high lose potential) match or make him pay for ruining my plans.
Well... I picked Varus mid and rushed EoN, I swear I've never seen such a desperate Kassadin in my whole life, I even roamed more than him and had 40 cs advantage while also being 5/0/3 at the ened of the laning phase.
