Dealing with high level enemies as hunters is a lot more gun skill I would say but I don't think the other two classes have any other better advantages towards bosses and such anyways. But as far as supporting, well you're half way there. You've acknowledged the fact the GG and Arc Blade are useless against anything yellow so don't bother. Be the mob clearer. If it's what we're good at might as well accept it. Arc Blade does well against red mobs if theres no light switch modifier otherwise slap some invisibility perks on that Bladedancer and your playing medic. Just be smart about it, don't try Arc Blading your way through the VoG when there's Fanatics and Supplicant s that will blow up in your face. GG I like to have combustion to get some extra damage on the enemies around the target otherwise just pick 3 (or 4) unlucky reds and fire away. Again with a VoG example, works nice for clearing Supplicants during Atheon or helping out with the troops in the portal. If you want to use it on a yellow, go for it just don't expect any great results.
