I've come to the conclusion that adding minion aggro on spells could have been a positive change
If the minions didn't proceed to chase me from the enemy turret to my turret and just suicide under my tower while being aggroed on by several of my minions.
Like seriously, as Anivia for example, you E the opponent and for whatever reason 1 minion for whatever particular reason is more mad at you than the others and just aggroes for way too long.
