I never said "highest" cost bracket, I very clearly said "average" IE: if you added all the champions together and averaged out their costs.
A'ight then, let's do it by average cost. There's 34 HoTS heroes, which cost a combined total of 229,000 gold; this averages out to 6,735 gold per hero, or 27 hours per hero of average cost for HoTS.
It would take 7800 + 6300*32 + 4800*34 + 3150*24 + 1350*21 + 450*12 = 481,950 IP to buy every LoL champion; 481,950 / 124 = 3886 IP to buy a LoL champion of average cost, which at 110 IP an hour, would take 35 hours. HoTS heroes actually take less time to buy, on average.
