DeacHead, I'm no expert on Star Wars physics (like how much gravity there is in space), so take this for what it's worth. Your tactics complaint wasn't bad narrative made sense on two levels: I don't understand the bolded. If you're looking for a response to this specifically, please restate.
First, I'm not sure how else you get that much pay load to land on a target from afar. One bomber took out an entire dreadnaught ship from above. This (delivering heavy ordinance from afar) is a thing we humans are able to do in 2017. Like I said initially, I let this one go, as one has to do with Star Wars because adherence to actual physical laws is not even remotely important to the franchise. In this case, they wanted to add in the trope of WW2 bomber that couldn't deliver the payload so someone sacrifices themself to make it happen.
I moved on from this pretty quickly.
Second, Leia herself criticized Poe for continuing to use these tactics after she ordered him to retreat. She wasn't criticizing tactics, the issue was him disobeying direct orders. If you want to say that disobeying orders was his tactic, then uh, ok. All bombers were lost so scoreboard says this turned out to not be such a great move.
I'm not sure what you mean in the second one. They were tracking the cruiser. They knew where it was not where it was going. Perhaps you could just explain more. The objective was to destroy the Resistance fleet. Hux's plan to achieve that was to let their ships run out of fuel and he'd pick them off. The FO did know where the Resistance was going, Hux was tracking them. The FO knew that, at best, the Resistance could execute one more hyperspace jump. Star Wars doesn't go into the details much, so I'm assuming they have some sort of astral coordinates they use for determining location. That's a pretty safe assumption since they make precise jumps every time we've seen. Hux knows where his fleet is, he knows where the Resistance fleet is. It should be a trivial enough thing to request additional assets at specific coordinates or even have one of the half dozen or so (I didn't count precisely) Star Destroyers with him make the jump just ahead of the fleet. Obviously this can be done because that's what Laura Dern did.
One thing I liked is both sides used good tactics overall and only bested the other through excellent maneuvers (i.e. Hux tracking, Luke's stalling) and Snoke/Leia called out any major screw-ups.
I love how this film echoed many Empire plot points will making them unique. Like Rey leaving her training to confront Kylo Ren was very similar to Luke leaving his training to confront Vader, but it was very much its own thing.
