Here's my idea:
Techies aghs: Pinpoint Activation
Adds an ability for Techies to activate Sticky Bombs. Cannot be used while dead.
Upgrades: Sticky Bombs
Bombs that do not latch onto an enemy hero persist for 2 minutes, turn invisible, and have a small amount of mobility. These bombs will not latch until they are activated by pinpoint activation, at which point they will act like freshly thrown bombs.
Since they activate like normal "freshly thrown" bombs they'll only latch onto nearby enemies who can then activate BKB. This will remove a lot of the bad feelings when playing against green bombs. Moreover, since pinpoint cannot be used while dead, it gives the enemy team to still push while Techies is dead. AND ALSO this would incentivize diverse Techies builds and adds reason to get the latch talent, which is currently never picked.
Valve, Use my knowledge I beg you.
