Invite reg is more referring to the fact that you guys have people spamming anyone who can block on steam to join your reg. Just recruiting anyone that is good and active in the comp community makes your regiment more of a groupfighting team/melee stack than a proper regiment. They just play in 92nd because you guys currently have the highest chance to beat 15th. If pieter leaves the scene again, another reg will take your place and all the meleers will go there instead. Its how its been for 2 years now.
