I do care when I'm watching, and trust me, the majority of the dota 2 fanbase agrees, because they want to see flashy, big combats with huge combos, not boring and cheap tacts like this, because it is not entertaining, and this is showbiz
Btw, to the "they didn't use bkb when they tp" guy. There's a combat waiting for them down there. What you suggest is they use bkb when they tp and not in combat. Their positioning was the main issue with their tps, they were all stacked up and not very far away. If they just stepped down a little and scattered, atleast 4 of them would easily make it back. That was the one grave mistake they made while Alliance got screwed many times (well, see their 3 man ganks on alchemist, combat wipes, getting dominated by dendi's TA) Na'Vi did one mistake and that cost them the game. There is only one hero that could cause such chaos on the opposing team and that is furion and his pushes, that is exactly why it is a cheap tactic, I don't get how you guys fail to see this.
