Yeah, I'd be able to deal with the stupidly widespread glove damage if the injector's leech effect wasn't minuscule. Safer to stick with a tempest coil in my opinion, even with the max skill damage increase. Losing the health and armor from having a shield is pretty problematic when you're depending on longevity through heals and kiting.

Having pvp'd as every class, I can honestly say I have to work 5 times as hard to stay alive as an Engi.
