It's worth pointing out ..... the gauntlets FFG introduced weren't cortosis (last I recalled). I suspect there was a balance reason for that.
F&D pg 172, Melee Weapons
Cortosis Gauntlets (Refined), Cortosis Shield, Cortosis Staff (Refined), Cortosis Sword
It's like Yogurt and the Schwartz up in here. "Cortosis the T-shirt, Cortosis the Coloring Book, Cortosis the Lunch Box, Cortosis the Breakfast Cereal, Cortosis the Flame Thrower!!!"
Yeah I hear you. It reminds me of playing Knights of the Old Republic. "What the hell? We can fight Jedi with regular swords?"
"Oh sure mate, we have this Macguffin substance called Cortosis. Now in a spray bottle!"
Actually I would consider the use of Reflect even with that shield thingie to be a display of Force Sensitivity. When this player was doing some undercover work I made it very clear that reflecting a blaster bolt, even with gauntlets, would be as much cause for alarm as whipping out an energy blade. Obviously one is more subtle, but he still only did it in situations where the other player would have gone "Full Saber".
I think part of what bugs me, is that Cortosis Gauntlets seem relatively common, and very easy to conceal. It doesn't say that they look any different from gloves you'd wear for any other reason. Whereas a Lightsaber hanging from your belt really can't be mistaken for anything other than a Lightsaber. So while your guy may draw attention swatting Blaster Bolts out of the air, he's just another guy the rest of the time. While someone with a Saber is more likely to draw attention regardless.
I was talking about the sheild gauntlets. They aren't corotis and I imagine there's a balance reason for why they didn't combine the two.
As for PCs equipping nothing but cortosis gear because rarity isn't factored in at char gen, GMs have final say over the final char sheet. If the GM doesn't say no then PCs being all decked in cortosis is his problem.
