For example, you never see 3-1-1 lanes, level 1 Rosh attempts, dedicated roamers and so forth.
3-1-1 is dead. That one's out the window just because of how exp is divided and pull camp positioning.
Rosh 1 attempts only happen in very, very specific drafts. And it doesn't help WK's W stopped being an aura.
And I was considering of playing Enigma jungle, because of how the eidolons work, right now, but there is no offlaner that can solo his lane - so that's out the window, too.
Creative dota still happens at Herald or Crusader level. But anything above that, you just have 20 years of accumulated experience that shaped the game. Not to mention that time, ehl oh ehl, when they matched players vs the A.I. and everybody learned some new shit.
