I believe I'm responsible for this lil' balance issue as well. On the RM side, I personally didn't have trouble with the indies, but we discussed with Seth who to bring and who not to bring to avoid the usual gankage we have to face during our fights against any LN entities (mainly due to the fact that the LN indies usually swarm the field).
We wanted a fair fighter fight without any caps coming in and spoiling it. The Battleships wanted a duel. The cruisers wanted a duel. Fair? Fair.
What if the LNS caps burst into a fighter fight with BCs and Dreads? It may make sense in RP, but it would totally spoil a fair fighter fight. Since the RM only had two caps present which fought the other two caps, a swarm of LNS vessels into a fighter fight would have spoiled the whole thing.
I have no idea what exactly happened in Texas though that created such a feedback, but I appreciate Seth's efforts to keep things clean.
