clearly SK can handle more than 4 knights at once so why not bring in an SK version of raids, large group(scaled down) dungeons, 5-8 man level sets
in other MMOs large group encounters and raids make up the bulk of endgame stuff and they are pretty good fun
So even though it would be a big undertaking making a few big group level sets (3-4 depths each, like boss levels, possibly playable in multiple tiers) would add some great group/endgame content (unlock access at certain rank?)
i dont think that current levels would work terribly well for group sizes much lager than 4, maybe 5, so they would have to be new levels designed specifically for large groups, with a minimum of 5 knights required to play (go solo being disabled and kick throws back to haven) and multi knight puzzles, hit these multiple separated switches within 3 seconds to open the door is enough (but more complex puzzles would be super)
since there will eventually be an arcade redux perhaps large group dives can added as part of the arcade, a 5th gate as it were - they could also work as prestige missions but then they become once a day kind of affairs
the enemies would need to be reasonably varied as well, dont want every knight bringing the same gear every time, still have a theme and primary family but have most monster families appear so that while some knights can take on beasts others can defend against gremlins and yet others bust up some constructs, hopefully a good variety of weapons will be present
aside from being hopefully challenging and good fun with a small mob of knights if incentives are required perhaps the payout from such large levels could be higher and/or unique tokens dropped upon completion, surely there is new equipment being dreamed up that could be token based
(alternatively the could drop krogmo coins, it isnt pvp but it is group content...?)
Boss Raids is a pretty cool idea, you can actually apply this to pretty much any mission and scale up the enemies health and damage
This would be nice "missions 10-X" content to provide more of an endgame, it would be cool to see
you can add a new form of token, maybe like a Raid Coin that would allow you to trade you raid coins for reskin costumes and weapons or allow you to trade for unique materials or recipes for the original boss tokens in case a particular recipe is just never there for you and you don't fancy bringing out 100k cr for it
i always thought the problem with OCH was that it never felt like the 'epic' assault until you got to the seerus fight, having a 12 man raid on the grand arsenal would feel more realistic than a 4 man group just waltzing in and wrecking everyone inside
only problems i foresee here are intense quantities of Lag and major EXPLOSIONS, imagine like 9 nitronomes going off with Polaris spam and then everyones game crashes because of that many particle effects going off at the same time, maybe have mission specific loadouts for the group to decide so they can prevent the insane screen nukes? like a Striker loadout would have a Acheron and a Leviathan, a bomber loadout comes with Graviton bomb and Venom Veiler, a gunner loadout would have the Umbra driver and a Valiance, a guardian loadout would have Suduraska and a Callahan, and so on and so forth
either way, +3 for raids, -1 for Screen nukes
