Only reason to hate HPA or any other type of airsoft gun is if your a whiny knob cheese and you got owned by someone using one. Bitches be jelly.
As long as it passes chrono then who cares, doesn't matter if it might get a few more FPS from joule-creep or similar, there's plenty DMR and sniper out there doing leagues higher.
Everyone seems to try use as heavy ammo as their gun will lift these days anyways and the heavier ammo is only reason something will hurt more. HPA lift heavier easier. If pains the issue people should bitch that everyone should be forced to use 0.2g instead, why limit the argument to HPA?
HPA might have potential for silly ROF but AEG's can do a ROF silly enough to make no comparative difference.
None of this stuff will make a significant difference to you getting shot or not, that's down to your actions and the other guy behind the trigger, so def agree with it not being the guns fault in the OP.
People seem to take good care of their guns in UK, so all that OP talk of 'it's cos your guns poorly maintained and dropped 50fps' seems irrelevant. People pay attention to chrono's here, and if anyone finds their guns dropped they'll get right on it, sending it to a tech if they don't know themselves.
Haven't seen a HPA setup last a whole day skirmishing yet, so even if you hate them just wait for the guys gun to break half way through the day and then get your revenge when he's reduced to using a 30rd semi pistol.
But anyways, why do you care, thought you were quitting, something that def needs to be announced, again and again... Yawn, you aint going anywhere addict, here's a few bb's to stop you clucking
