Let me just give an example of what in my understanding GOOD siege is.
Lets take situation when you are in own Borderlands and enemy holds fully fortified Hills. Mortars, catapults behind gates, trebuchet at the vista, ballistas at the choke points, lots of supplies inside.
For attacker it should be impossible to even try taking it if defender is capable, until they slowly drain Hills supply.
So a siege starts with attackers taking both supply camps, and probe of brute force attack – which likely will be repelled. Attack on north gate would be suffocated in poison treb fire form inside the keep and concentrated mortar fire. Attack on South gate would be futile to begin with, because of how easily the gate is defended.
Thus attackers build trebs and try attack from distance from different points, however enemy either suicide runs to destroy the positions or countertrebs (even stealth treb attacks, like building treb behind attackers positions to destroy their own). To defend own siege weapons, attackers build defencive siege weapons like balistas and carts at own positions too.
Still, its hard for attackers to hold trebs firing for long, so they resort to instead trying to drain resources of KEEP by sending smaller groups attacking the keep gates and walls from different positions while main force blocking keep reinforcement and supply income – with Keeps supply slowly draining on repairs.
Defenders to distract attackers, send strike force to attack their keeps, trying to make the attacker force move away and get supplies in keep.
Eventually attackers however, breach in, move in – but are greeted with ballistas on choke point and arrow carts. While holding the gate/wall open, they build treb behind, and treb the enemy defensive positions. They still however cant safely attack the gates, since the trebs placed in inner circle, are shooting their positions and destroy their siege weapons. So instead they place catapults on the wall, where treb cant reach them to shoot the gate, and a treb to shoot poison inside the inner circle to destroy any siege weapons/positions they may have behind the gate. Meanwhile porting Golems from Garrison, and stealth attacking the other gate which falls fast, since enemy fails to notice it in time.
Both gates breached, the go to Boss room just to be greeted with massive balisstae fire at chokepoint entrance. Only few defenders remain inside to defend the chokepoint for a minute, while rest ports out and runs to attackers keep with main force, using moment to try to either take it or make main attacker force pull away.
Attackers are forced to pull away to defend, however return later, send Golem to chockpoint to attract all the fire, and send mesmers inside to open portal, after which portal bomb remaining defenders.
THIS is how a proper siege with both organized forces should be conducted. If objective is defended, taking it should not be easy, and HOLDING and DEFENDING something should be relevant.
What we have now instead?
3 zergs of people run around the map mostly avoiding each other, taking empty keeps. Any defence and upgrades are meaningless. There is nothing that cant be overcome with brute force of few siege golems.
If you took objective, you should value it and defend it. Loosing it should be a wound, not a trivial thing. Supply lines should matter, proper siege conduct as well. I really dont get arrow cart whine, especially as its not really the stopping factor – even proper balista defense on chokepoints is better, and people fought much harsher defenses before where there was no siege limit and before AC`s nerf. No 2, no 4 no 10 arrowcarts should be able to stop or even really slow down a proper organized force. So for me most of complaints basically are read like “i cant stand in red circles anymore! fix it!”, while those weapons were created specifically for exact this purpose – anti personal weapons preventing people from just running around like zombies and pressing 1 targeting gate.
