I've once joined a guy with active recruitement once, I think it took over 45 minutes before someone decided to join via the "Join quest in progress" while some other peeps were asking to leave some room for other players to join. Party leader declined affirming they were being usefull for healing and Buffing, Except we aleready had a Techter/Bouncer doing that exact job...
It's also realy frustrating when you try to get in a lobby and when you arrive, you see a guy with 2 techter or something, then comes around a 2nd person with the same setup, and yet, It takes AGES to kill any boss mobs you come across because of the huge lack of DPS...
Plus The "Join a lobby in a other block" tend to send you toward lobbies that are about to get full. There,s been a few times where I tried to find another lobby to not get stuck with some "Slow runs" as i call them, only to get into an empty lobby (1-2 players out of 12) then try again to get shoved back into the same game with the guys running bots.
Instead of using bots for "Clearing the boss", you can simply ask the teammates you are with if they want to warp up the laps you're running around with them. Most of the time, they will just agree and help you kill the boss before hopping in another lobby. I've never seen someone refuse, and if they aren't happy with it, There's two solutions;
Leave the party and wait for slots to open up. when they do, Place a telepipe down, Summon bots, get back through telepipe then straight to the boss.
...Even doh this method has alot of flaws as; 1a: The Castrum demonica has no "Aggro" to speak of, only huge AoEs. Making bots useless as meatshields. (Plus you'd do so much damage they woulnt even hold aggro.) and 1b: Bots Damage are reduced by a good 3/4 and wont use techs/PA as often as they should.
Heck, Giving your mag the ability to buff yourself randomly and feeding it before going into the fight would be more efficient.
Join the map with Aliance members. Usualy if you are in good terms with them, they wont be too stuborn and will probably decide to stick with you.
Oh you can also go solo the boss, I mean... I did it plenty of times. If you're propely equiped for it, It should be finished under 3 minutes and you wont risk dying either. The boss ususaly deals about 20-30% of my life in a single hit, Leaving me plenty of time as well to recover some HP with Resta or a -Mate item / Star Atomizer when i'm dry on PP cauz of a error of judgement.
Plus I'm more than certain that 2/3 of his HP is located on his head, So once the two arms falls off, it's only a question of time and patience until you get through it. Certenly beats leaving through the ship even doh I thought than doing so still gives you your Dark Blast EXP...
... I know im rambling more than anything, but to make my point clear;
I think SH difficulty is no place for Bots. If i would see them in SH, Sure why not. because you don't absolutely need efficient teammates to succeed, but UH ABSOLUTELY requires efficient teammates to proceed, especialy since maps like UH Woods , Corrupted Navarius, Etc... are mostely farming maps, it feels realy selfish to see someone go with bots for something that will only benefit them.
Or in other terms; This is a MMORPG. Later Content for the game scales for Multiplayer in mind, Thus, "Solo player" Is a term frowned uppon.
Heck, Even I, as a Level 90 Hero, +35 Atlas Talis, +35 Atlas Sword, +35 Dual Birds (All 14 star weapon) , Along with +10 Units , I know that i can't solo bosses without wasting over 3-5 minutes per encounter in those kinds of maps and NEED players to help me out.
If you want to solo that bad, There's also an option to allow Only friends/Guildmates to join. Just enable it.
EDIT: Oops. I meant UH, not XH. Also meant that my weapons were 14 Stars, not 15 stars, lmao.
