Increase in DMG/CDs reduce obvious Windows of Power; thus creating a steeper learning curve for LoL.
Which at first appeared to be an odd direction (in my mind) for Riot to take -- until I considered how many players are Bronze-Silver. But in short, it'll make understanding opportunity more difficult for newer players, and blurs the lines of good/bad decisions. As well as leaves low-elo players genuinely feeling as though there are no options against a powerful opposition.
I could make a hundred posts about why this game's direction is detrimental to players old and new, but god I feel like I'm wasting my breath as the days go on.
