Veigar's passive needs to be reworked
For some reason this is not self evident, but veigars passive is absolutley broken. If we exclude item passives and accuracy for simplicity, then 20 to 30 Gold translate to roughly 1 AP in itemization. Including the items passives of deathcap for example(a core veigar item), then we easily reach the equivalent of 30 to 45 gold per 1 AP stack. Assuming that veigar can kill about 50% of all minions with his q and using the most generous estimations for gold efficency, veigas passive generates almost twice as much gold as twisted fate's passive, and every second minion suddenly gives twice as much gold as well. The real numbers are undoubtedly higher. And this does not even take into account that this "gold" is stored as constant ap, basically a free second deathcap as 7th item that gives around 300 AP at game end. This insane stat boost, far out of proportion to almost every other passive in the game, results in you getting instakilled from one q + w after 25 minutes. How people are not aware of this insanity is beyond me.
