Ok, so since the majority of people in this topic appear to be too dense to grasp what's wrong with ballistas, I will, contrary to what I said in my original post, try my best to explain why they are bullshit.
Basically, there's three types of ballistas:
A) The ones which will shoot at you at your spawn or maybe like 3 seconds away from it.
Certainly the least common but the most useless ones at the same time. You spawn more or less instantly and also frequently closer to the castle/flag compared to where you got killed. There's zero (0) defensive value in those ballistas. Usually they require some skill to aim and don't forget to take the missed shots into account. These ballistas contribute more to the attackers advance because people will spend time reloading and aiming them with no advantage whatsoever for the defenders to be gained because the same people could just be actually defending something.
B) The ones which will shoot you because they are aimed at a chokehold.
I can see the point and fun of chokeholds but why do I have to die instantly? Shields will only very, very very occasionally prevent you from dying. I can maybe recall like two instances where I had a ballista shot in my triple loomed elite cav with 6 shield skill.
Anyway, it's hard not to get hit by a projectile when in a chokehold so why does it have to take no skill whatsoever to score a kill? I could live with receiving a headshot because that acutally takes skill so why this? Just why?
C) The ones wich aren't aimed at a chokehold and can't pick you off of your spawn either.
You might say they acutally require skill and I do agree with that. And that's also exactly why they are bullshit. It's because you will only score a kill every now so often with these ballistas. People will waste minutes of firing into thin air, minutes in which they could actually be helping their team in one way or another, but no, they prefer to mindlessly reload and not to kill anything.
Apart from all of what I just said, why do people with full melee builds have to have access to ranged weapons (I remember when there was no WPF requirement for throwing weapons and that got removed for a reason)?
It basically means that all the levels and melee gear and skills and whatnot will go into something that could be done by anybody. Also why do noobs aka peasants need to be able effortlessly kill anybody? Because it's either no effort whatsoever or wasting minutes that could instead be spent on trying to help the team or just, you know, trying to learn how to play the game.
Was there a problem before the introduction of ballistas with attackers winning rounds too fast? If so, I highly doubt ballistas changed anything about that. They are a zero sum game at best.
Also, I know that I didn't mention ballistas for the attacking team because it's so rare to even see somebody using them (let alone kill something).
