How to fix boss skipping? Easy. Second that works with bosses would be a door that opens when the boss is killed. Thats how they do it elsewhere.
totally agree here. design instance mechanics that require their killing to progress further on. the more established mmo makers have had this for some time.
a similar idea is to make them part of the quest itself. much like the h4 bh quest.
or make each boss drop the bh coms and have the daily reduced to one or two.
the root of the problem is with the bh coms in how they are earned and the process of instance progression. if you change any one of the two, the solution to skipping is rather simple to solve.
