Hmmm, this guide is great indeed, but i see it applicable only in aggressive play and whenever your carry (probably the whole team) is aggressive and skilled enough or else it will result to a dire consequence. And also not applicable when the enemy is equally aggressive where vision can turn table. Yep, his ult is a global flare, a homing nuclear flare, although considering its high cooldown, i think vision would be delayed, and can somehow interrupt certain ambush tactics due to the fact...
