Some classes/players walk through a fire pit without hesitation and come out the other side unscathed, while others fear the them regardless of the shields available to them. I've seen Bounty Hunters back pedal their way through a fire pit on full blast while their health bar barely moves. Unlike others who better not spend one second in it or else forfeit 50 - 75% of their hp.
I know, some classes have shields, bubbles or are tanks or have better survivability. Why wouldn't they be more resistant to the flames from the fire pit? Because it is an environmental hazard that has to be taken into account when attempting to maneuver through the course. Each side of the cat walks has fire pits alternating their timers, that needs to be considered when moving through them, passing, or receiving.
My question is should some classes have an advantage over others when maneuvering through these hazards? Are the fire pits working as intended? Was it BioWare's intention to make some classes fear the fire pits while others can just shrug them off?
