PRE WARNING WARNING. This shit is forever.
No kidding.
Kinda sad it didn't go over tower Aggro though, as that seemed to be the main thing I struggled with when picking up DotA.
Towers there attack the closest enemy to them that's attacking them back.
Minions prioritize not-structures over structures and will all peel away from smacking the tower when an enemy wave comes there way.
Makes striking towers as a melee hero pretty awful, but inversely makes diving enemy heroes as a melee substantially easier: with proper timing towers aren't going to lend any help and you can just destroy someone under their tower.
That said - probably gonna stick with LoL.
DotA and DotA2 are solid games regardless of how you look at them, but I still feel LoL has more going for it.
