Hebrews 10:31

Turn the DotA and LoL players against each other. This is laughably easy.

You say that, but while the hatred from the DotA community towards LoL is well known and widely documented, LoL players feel at worst apathy towards DotA. The charred bones of Rhuax of the Fire Below estimate a mere 14% chance of being able to get them to stop attacking us on account of infighting. We can improve this to just over a 70% success ratio by assisting DotA in the massacre of the League of Legends in exchange for peace, according to shells scorched in the name of Zhurong of the South. Better still, if we can co-opt the strongest of the Defenders of the Ancients to our side, we will be able to empower ourselves further while simultaneously making the remainder of the DotA faction easier to destroy.
