Swats are not weak but they are also not a good choice for new players who don't know anything about the gamemode or have 0 samp skills and for major/armor fights.
They have different purpose than main fighting classes, I go swats sometimes when I'm not interested in direct fights. I use it for sabotaging/delaying terros, for example- messing up the airfield, pushing their cars in water in fc, damaging and puncturing their vehicles before they encounter cops ( using vip sniper), stealing hydras from lv airport etc, plus they have good weapons from all classes thus making them a good choice for solo players, deagle for finishing off the fight, shotgun is better for damaging terrorists and their inaccurate aks at longer distance (I find shotgun easier to aim that other assault rifles, at least when target is in mid range), and tec9s for main fight and if swat has vip weapons like sniper then its better than main fighting classes in some ways.
But of course nobody uses it that way and like I said, it's not suited for major armor fights, 10vs1 or for new guys so Better remove it than making newbies RQ from weak weapons.
Maybe Mia's suggestion might convince others to do something about swat class, even though it might be just to oppose her XD.
