The biggest problem with Firefall currently is that they have overemphasised PvP at the cost of the PvE experience.
eg. a tiered system rather than levels, no loot drops, fairly flat performance increases in PvE performance etc.
Because even the hardest (eg. melding acolytes) PvE mobs can be gamed once you know their tricks and weaknesses, it only takes a very basic shooter skill set to be able to dominate PvE even in a T1 frame.
I keep hoping they'll do a Guild Wars 2 split for PvP/PvE performance to allow vertical progression in PvE vs horizontal in PvP, but I'm not holding my breath.
Asmodai aka Saviourself aka Stabbitha aka Azshadoria... or Azsh... Azshaz?
