Talon nerfed because his burst pattern should be gated by a long cooldown ability...

Talon can't have his ult that requires him to suicide into the enemy team on a 50 sec cooldown but it is ok for Lux to kill 3 people from the fog of war every 30 seconds.
I mean Lux's ult is just a long range nuke. Talon's ult is a greater practical AOE that puts him in stealth and gives him an MS buff. Lux can't nope out of a situation with her ult, save for get the kill, but the same could be said for Talon. He gives up some damage for a lot of utility, and end game with a 50 second cooldown without any CDR assures that he'll basically always have it up.
