on Shards of Dalaya (the almost abandoned old one), people made alt clusters for each of the level locked bosses, then /locked the account (where you couldn't trade their items or accept new items or whatever else). and parked them at each of the level locked names (adepts).
They then twinked them with literally the best t wink gear they could possibly make. for the early, like sub 40ish i think.....ONE of these alts could solo the thing. so because it's a box server. you could play one of those alts, and your character. do that with the alt every X hours (respawn time) till you get youre item then move to the next.
The new Dalaya, i'm not sure about, but they did remove the irreplaceable items from the adepts. so it's just a choice to do it or not. i basically never did it because it was real obnoxious waiting on the respawn, then trying to get in when some guy could just log the nuclear alts in and just kill it immediately.
i think literally the exact same thing will happen on the box servers. people will make turbo twinks and leave them there. i doubt they'll share the account info for them tho because it's an actual sub and not a free infinite account emulator.
