If anything, changing the guards to be so ridiculously powerful did nothing except make siege even MORE geared toward only endgame guilds.
+1.
i know some guilds that already had a challenge with the guards. they have since quit doing SW.
that being said, i believe all the pve elements of SW should be doable by even a lvl 1(exaggeration), using SW-specific items(catapult that can effectively kill npcs for one). SW is (imo) a player verses player event, but with the emphasis on pve elements detracts from the overall "pvpness" of it, and thus, caters to those who can easily do the pve elements verses those who struggle with the pve elements. if anybody has ever been in a low point SW, the guilds spend more time fighting the guards/balloons than they do fighting each other, simply because to win you NEED to perform the pve actions.
some1 posted what i assumed was a troll post, yet i agree with them. take out the guards, take out the castles. make SW a giant game of karros canyon. either that, or add(and thus, balance) elements that allow an ungeared, lvl 1 char to participate fully in the pve experiences, instead of choosing between getting 1 shot by guards or getting 1 shot by players(siege engines is a great idea...they just need help, or make more variations). point is, give the pve aspects even more SW-specific strategy. add more herald-style positions, that are not necessary, but allow a lvl 1 char to actually play(something like the transformations from origin 2nd boss come to mind, scaled to current SW, or the transformations("flag") in the other arenas after stone is captured). something that loses potency the more geared/leveled you are(set values for skills, ISS-style, comes to mind, so not to scale with current gear).
yes, lvl 1 char is an exaggeration, but you get the point.
dunno if it was this thread or another, but to the point of tower capping time: increase total time to cap a tower to 45 seconds, and leave fearless where it is. in addition to that, change capping to a more fps-style capture system, in which you have 1 person capping, it goes normal speed, 2 people capping, double speed, 3 people capping, triple speed(3+ people required for a fearless cap), etc.
i know i kinda rambled, and my post prolly doesn't make much sense, but whatever.
