I have two issues with this talent tree when I first glanced over it just now.
Basically, it's a non-lightsaber talent tree, but it provides two lightsaber only talents. Now, with reflect it isn't perhaps such a bad thing, it's a 10 XP talent that could be useless to you, but it's only 10XP and while this does make the route to dedication more expensive, it's not a big loss. The culprit is Saber Throw. This is a 20XP talent. Now, you don't need to take it certainly, but to me it seems rather meh for anyone but a lightsaber junkie if one of the higher-up talents is suddenly useless to you. It is arguably shoehorning players into taking up the lightsaber.
There isn't one solution to this, I mean, you could leave as is and sort of shaft those aggressors wanting to use melee weapons intead - they have to pay 25XP more to reach Dedication, which isn't much of a deal perhaps, but I find it silly basically.
Another solution would be to replace said talents, I suggest Parry in place of Reflect, it doesn't require a lightsaber. Of course then there's the question what to do about Saber Throw. Replacing it with what?
A third solution involves changing both Reflect and Saber Throw to be allowed with melee weapons too. Just now I can only think of one instance where Reflect could be said to be used by a non-force sensitive, and that's Crimson Empire (1 or 2) wherein Kir Kanos is seen reflecting blaster bolts with his double bladed vibroblade. Of course we don't really know whether he's force sensitive or not, it is never mentioned in the series - and of course one could argue that the depictions of him using his vibrostaff thingy for reflecting blasters is just artistic license and cool narration.
As for saber throw, I cannot think of any instances in Legends where that is used with a melee weapon, but I could of course be wrong.
Still, I think that would be the best solution really, they're both force talents, which means the force is involved and that in itself could serve as a basis (I guess) for saying why a melee weapon culd withstand a blaster bolt or similar ranged attacks. Although, I'm not certain I'd let melee weapons use Improved Reflect, which now suddenly becomes a possibility as things are currently worded in the beta book and the update.
So, there, initial reaction to having the beta.
