The situation still comes up though many tournaments allow round 1 grudges where you might know but this is balanced by later rounds.
You can try varying your lists even within a faction.
A list focusing on infantry and destroyers is going to perform very differently to one centered around ctan.
It is also why I would recommend tourney practice because if your practicing what you would run for a tourney your not going to run an anti faction list
