I didnt know speed was so effective. The chasing capabilities of her and sakke1's oak with wrap are unreal. The match where they are so behind in warscore but then turn the game with giants out is very impressive. I was like: is this really happening?
It's only super effective in 2v2 matches where ganking is more difficult, and the position and location of the 2 players is essential. If you watch the Sedna, once she gets Journeyman's, she will actually run into the archer towers to proc it, then run to your portal in about 3 seconds.If she sees an incoming portal, she runs back, you waste your gold -.-
Humorously enough, once they were at my portal and I was pushing theirs. Their Sedna managed to f'king run all the way across the diagonal before I could cap the flag (she started running as I passed the double towers).
I've never played against Sakke's build with my PM but when I do occasionally pug against them, I actually get the Amulet of Teleportation, which lets me teleport with reckless abandon. Speed stacking is very cheap (as opposed to being very strong but having to burn teleports all the time without getting into actual engagements). It's a war of a attrition and it's very important that you are able to chase them off any flag at any given time.
High level 2v2 is radically different than 3v3 (I prefer 2v2 and I try to play that more often but sometimes it doesn't happen). Creeps are more powerful and actually your main tower-pushers, you can only shop a few times the entire game, and speed is very very powerful.
