I find the whole crystal bleeding thing to be pretty stupid.
Emo shit. 😛
In theory, I have absolutely no problem with the idea that lightsiders and darksiders would construct their lightsabers differently. Let’s start with the premise that lightsaber crystals are alive and possess some level of sentience, that they have wills of their own and won’t just let any schmuck use them as batteries in their gizmoes. The Force-user would then need to get the crystal to cooperate with them. For the lightsider, this would involve a lengthy period of meditation over the crystal to form a rapport with it, requiring deep concentration and patience. For the darksider, they’d just use the Force to dominate the crystal, bending it to their will — the quick and easy path. But the difference between lightside/darkside lightsabers would be entirely psychical; they’d feel different, not necessarily look different. But everything pertaining to lightsabers in official canon has been thoroughly fucked up since 2002. Just look at how TCW handles a Jedi’s construction of their first lightsaber; the younglings go on an Easter egg hunt, then telekinetically mash the components together within seconds. Such a downgrade from how it once was tackled in older EU.
