Actually, League was made from people who'd played the original DotA and wanted to do something that was the same genre, but at the same time WASN'T just a carbon copy of the original mods to Starcraft(2?) and Warcraft 3. Thus, they took the formula and made it their own. DotA2, on the other hand, is a faithful replica of the DotA mod, albeit as its own game and more variety in the heroes. The original purpose was NOT to make an "easier" DotA, but rather to take a game that was regarded as great and making their own game, streamlining things along the way. Making a simpler version of DotA is what Heroes of the Storm is doing.
