The issue that stuck out with me the most was the fact than Mon Mothma's plan not to destroy the communications installation but instead to bug it was completely and utterly sensible. I suppose I can account for Ezra's impatience and urge to destroy it by his evident still ongoing immaturity. But in the case of Hera?!? That was eyebrow-raising to me. How is it that Hera just wants to blow shit up; can't she see the strategic advantage in a) exploiting the Empire's network, especially for something they could easily replace, and b) not tipping off the Empire as to what sorts of sources of information the Rebellion might have?!? Geez.
She's having a problem seeing the long term advantage over the short term harm they can do. She just lost a bunch of people under her command on the mission at the beginning of the story (offscreen). She's pissed, hurt, and wants to hurt the Empire back. It's her recognition that Mon Mothma's strategic decision is correct that keeps her on mission even when she agrees with Ezra and Sabine.
It has to be an ongoing problem for people in situations like this. You keep losing friends and comrades, and what little you do in the long game hardly puts a dent in the Empire in any real way. Whereas if you blow the relay to hell, you get the satisfaction of watching them scramble over the fallout for a bit before they rebuild it and you're back to square one. One is the correct decision, the other one feels good for a bit before it gets you nowhere. But I totally understand the temptation.
