I would honestly expect nothing less from weapons obtained from essentially the God of Fire. The weapons glow like an ember, that's pretty tame IMO. The only other way to really convey fire would be to physically set the weapons ablaze, I think this is the better approach. If the effects were any more subtle then they would be quite dim and would just essentially be black weapons.

Honestly if you don't like the direction the game is taking that much, it may just be time to cut your losses and call it quits. This is the way things are going, it's not going to stop.

The current equipment is far too bland for my tastes. I always justified it as being the base equipment and essentially just what they're throwing at us until the cool stuff comes up. I was pretty disappointed with Flametongue being just a normal sword, it should have had some kind of indication of its namesake, you know like how it is traditionally in FF. Excusing the current gear's bland look as "artistic direction" is a pretty lame excuse. The gear we have now is recycled over and over and occasionally changed slightly. Going back to Flametongue, it's just a slightly modified version of another sword we currently have.

The game needs more unique looking gear, and if that means the weapons from the God of Fire have an ember glow, I'm okay with that. The weapons should convey the power and look of the boss they come from.
