Reported for afk in BG

So like.....I was reported for afk in a battleground where it just begun, it's the strand of the ancients I'm guessing? The one with the gunship that takes forever to get to the enemy base and start fighting. long story short, the report happened at the start of the match, I was running to find people and they were dying before I could enter combat and I was kicked out of the BG + given 15 minute leaver debuff......

This doesn't seem fair when a player is actively participating in a battleground and kicked out because he can't enter combat fast enough.
