That's making a lot of assumptions about someone that we know barely anything about. We know Thane is trained in hand-to-hand but we also know that he is an assassin and from a lot of info, sniper by trade. And there was nothing wrong with the tactic. He used the gun as an expert close quarters weapon, solidifying even more his awesomeness. I guarantee you he took the sword only because of Kepral's. Though I believe there is a chance (very small) because he thought he had to. But he knew there was no other option. It's also not out of character. In his entire recruitment mission you hear him fighting in close quarters and it even ends that way. Thane knew that he had to buy time with what little power he had. So he did. It's quite reasonable to assume Thane knew how it would end because of his disease. The least he could do is slow down, weaken or hopefully actually take out the assailant.

Huddling together would have been hands down the worse tactic. It would only make it slightly harder for an invisible enemy to take everyone out one by one and even easier to do it two by two. Heck it would have made it very simplistic to line up any shot or throw to take out the target in the middle, because Kai Leng would have had all the time in the world while everyone just cowered like babies.

I'm not justifying Kai Leng's look. I didn't like it either. Just explaining what we were seeing. The Overlay is also equipped with an advanced VI. It could help in a large multitude of ways, not just targeting. It could let him see thermal, subtle body movements and more. I'm sure that he also only has a sword because they couldn't

As far as a Reaper taking control, the geth we have to assume are adaptive. Not saying its impossible, but hard. Otherwise, the Reapers wouldn't have "asked" (Sovereign) or been asked by the geth for help if they could have just been easily hacked.

As for the VI, didn't he mention something about security protocols? Not too sure, but that might be the "easy" loop hole for that.
