Homing Missile`s recharge time is wrong on level 2 and higher
When choosing the level 25 talent which replaces the cooldown with 3 charges, the recharge time is supposed to be equal to the cooldown on the same level. Be that as it may, when on level 2 or higher, only the very first charge uses the correct recharge time, while all other charges use the level 1 cooldown as recharge time, taking significantly longer to recharge than the first charge.
Ancient Apparition`s Cold Feet has this issue as well.

Rubick`s stolen Homing Missile copies the charge talent
Rubick generally does *not* copy talents of spells. Be that as it may, he does gain the charges of Homing Missile when stealing it, going against the rule of not copying talents.
The same goes for a stolen Cold Feet, where Rubick also copies the charges talent.

Homing Missile does not have infinite charges in -wtf mode
The wtf mode grants charge-based spells infinite charges. Be that as it may, it does not do this for spells which do not have charges from the beginning. This means that Homing Missile does not have infinite charges in this mode.
Other spells affected by this are Cold Feet, Rupture and Demonic Purge

Homing Missile`s recharge timer on the status buff visually resets when respawning, causing its cooldown to desync with the charges
When a charge is currently recharging, respawning during it causes the green sweep on the status buff icon to reset, while the actual recharge time is unaffected and continues normally. This can cause the cooldown to desync with the recharge time if the last charge is getting used after respawning.
Other spells affected by this are Cold Feet, Rupture, Stone Remnant, Fire Remnant and Demonic Purge.
