Black powder weaponry took a very long time to produce a hand held unit. It took more than 300 years for real Humans to go from a black powder propelled, hand held, projectile weapon to the Gatling Gun of the late 19th Century. GW2 is how far removed from the first game, which didn't have canons or anything like them? Why even bring guns into the game?
And why would the Charr be technologically advanced? Their weapons are made of bone and wood in GW. It would make more sense for the Asura to have exclusive use of guns.
But whatever. Maybe I am just a little miffed that guns are present in a Sword and Magic Fantasy game. Maybe I am a little concerned that a change like this is made, which, in my mind, brings GW to a more WoW like stance? As for not following the game, that's just not possible. I can try, though, to rein in my opinions if they bother everyone else.
Although I don't mind the guns in the game, it's the other explosives that don't seem to gel well with the rest of the professions. The engineer seems to be 95% AoE based, which may look OK on paper, but it will translate into 20 engineers plopping down 100 turrets, having 20-40 land mines setup, and lobbing grenades of all kinds like a squad of 4 assaults in BFBC2 sitting on 4 ammo boxes.
How long before that becomes annoying?
But I'm reserving my contempt until we see more gameplay from an engineer. The way Eric Flanuum (I think it was him) put it, he said that the Engineer wasn't THAT offensive, instead it relied more on crowd control and support.
But to me it seems like a spirit spammer ritualist with the TF2 medic healing gun.
