What? Mida is certainly a pve gun. For those that don't rely on "strat weapons," generally pve is played to a certain build maxing intellect and also armor, and packing weapons with reproducible and efficient dps... Mida on the other hand functions very well for the build relying on ability kills and orb generation over gun kills. MIDA is fantastic for the raid, strikes, and prison of elders. Being significantly faster moving than the ai helps a lot as much of destiny's pve challenge comes from navigating from cover to cover while setting up for the next move.

I'd say PvP players care. Believe it or not, there's a large majority of players who only play PvP, and whilst you and I may not like PvP, other's do and we should probably respect that.
