No "Enemy Pilot Locking" warning.

Am I the only one that gets this? I swear I can attribute at least 15% of my titan deaths to an archer missile that didn't give a lock on warning.

Sometimes in close range situations it will show the warning only briefly before impact, but thats not what I'm talking about.

Occasionally a missile locked onto a friendly titan will miss the intended target and hit by chance, but that is too flukey to account for how regular this happens. Sometimes in a messy fight I feel "maybe I just didn't see the warning somehow" or if the damage is not fatal it could be explained as a satchel hit instead, but other times it is as clear as day.

This is easily my biggest peeve in titanfall at the moment. Sometimes I'll go multiple games, only ever loosing my titan to pilot archer missiles with no warning.

Is there an exploit with the archer missiles I don't know about?
