What's the problem ?
Oh, i need to play better to win, sheet that's too hard...
I've been in most Fortress sieges, and i have seen Order killing Fortress Lord twice (post last patches, normal killing w/o any exploit).
First thing ppl need to understand is that, you finally should split zerg. Why ? Let's see, 140 Order push ChW but only 96 get in, while TM is free and open, why not push 2 zones at same time ? Why not open 2 Fortress at same time ? Why not let more ppl get in AND increase your chance to win ? ROCKETSCIENCE i know...
Second thing ppl need to understand that finally your WB should have proper setup and ppl should finally play properly (ACTUALLY USING SKILLS). You can control Fortress Lord with 4 ppl, 2 tanks with crossguard who use challenge to decrease hes damage in rotation AND use taunt in rotation to interrupt AoE Spinning AND 2 Healers who actually REMOVE/DISPEL curses like one which Decrease Armor to 0. BOOM SECRET REVEALED. Now rest of zerg can handle rest enemy forces, but still u need proper WB Setup: 2 true tanks (not pseudo 2hd dps tank) 2 aoe dps (not ST WL/WH/SW/ENG ) 2 healers (with more than 6k wounds...). Only then you can hope for victory...
Check my combat log when i was tanking lord (and it was announced couple times that im gonna tank lord), no single heal from healer on me. Last damage tick, yes 4k+, is when Lord apply Debuff that removes Armor from you, which healer can dispel.
Non single invade executed even once proper m4 push into lord room...
You have tools which you need learn how to use, its that simple.
Last time in TheMaw Order blob even managed to get into Lord Room but they failed to hold it, it's only on them to not be able to recover.
So please, don't blame devs and game mechanics that you are failing, because it's not their fault.
So far Fortress works properly and have no bigger issues, i wouly only suggest 2 things:
- timer of siege should be visible for both realms
- after successful defending Fortress, campaign should reset to middle zone, for example, when The Maw has been defended, open zone should be Praag not Chaos Wastes. (otherwise this can cause non defending mentality, 'let enemy push one zone we defend Fort again')
