1) make rank mission not playable more than once (included KoA and HoH) except upon invite
2) give missions like "Silent legion" or "Alone in the dark" a spot in the clockwork (dark city style)
3) lower the price of a shadow key
4) remove AA from lockdown
EXPLAINATION
Suggestion (1) wants to restore the activity of the Arcade section of the haven. We already discussed it's a section that's almost dead nowadays. Furthermore, missions like "King of ashes" have completely destroyed a huge part of the social activity of knights and made the CE price skyrocket to 8.5kcr. The fact that people can start such mission with two clicks also ruined the possibility to find fun and colorful levels to explore (except for those players who explore the clockworks for this purpose) and introduced a lot of staticity in players. The result is that some knights at the moment play for crowns and not for fun (this will be recalled later too).
Suggestion (2) wants to save the possibility of doing those missions after disabling rank missions. Otherwise it could be included in normal daily prestige (not danger) misssions list.
Suggestion (3) deals again with the fact that people play for crowns and not for fun.Shadow lair should be a moment of fun, not something to do only for interest to craft at the sanctuary. For example, you could split the cost of the key in two parts: one for the access to the shadow lair and one - at the end - for the access to the sanctuary alchemy machine. This will preserve the cost of crafting special gears to 1800 CE, but it will be lower for people who don't need it and just want to play hard levels.
Suggestion (4) talks about fairness. Some knights have ability to ditch attacks by moving around their opponents. It's very annoying to see that all this effort gets completely destroyed by a single random click out of a ton of click spams. In lockdown the most capable player (and team) should win, not the most careless one.
suggestion 2: Silent Legion has to be hands down the best levels of clockworks. It has to be in the maps. Not missions.
suggestion 3: Shadow Lairs are over rated. in my opinion, Danger levels are harder that SL. SL is just about timing and good computers.
suggestion 4: Im going to have to disagree with you on this one. Auto Aim is a compensation against players with HP trinkets, ASI VH UVs, and the sorts. If AA goes, so should bonuses, UV's, OP weapons should go. Normal Player (me) vs super P2P player with threatening looking Hammer ("pro"). Its a dead giveaway whos gonna win. AA makes it fair for normal joes.
