When a piece of gear shows its change to your DPS are all the stats considered (including magic stats etc.) or just the base weapon. Like if it has attack speed on it, is that calculated or something I'd have to calculate on my own
The DPS on the weapon includes the damage and attack speed (so increased attack speed is included), but things like STR, DEX, or INT are not.
When you scroll over it and it has the little green +numbers or red -numbers, that includes all stats on the weapon. So a weapon can have lower DPS, but still be stronger.
