Why Rabadons should have its cost reduced by 50g

Ever since the almighty Phreak graced it with his blessings, Trinity Force has been the glorious "Tons Of Damage" item. However, the item has unfortunately fallen from grace. Probably the main reason it was known as such was because it was the most expensive item in the game back in season 1 and 2, costing around 4087g. (Not sure of the exact price, but all I remember is that it was over 4k gold. The next most expensive was IE at 3800-ish gold.) But ever since the season 3 item changeup, Trinity has never been the most expensive item, constantly outdone by other items such as IE, Scimitar, etc.

However, now the great Trinity once again nears being the almighty overlord of items, once again being the most expensive one out there. Yet, the only obstacle in its path is that just 1 other item crowds the throne. And that item is the Deathcap, tying Trinity for the most expensive item at 3800g. This is why I propose lowering the cost of Deathcap by 50g, so that after 3 whole seasons of not being on top, Tons Of Damage can reign once more. So I beg you Riot, in the upcoming mage update please lower Rabadon's cost by 50g, and let Trinity Force regain its title once more as the king of items.
