How about...
A revert to old pre-patch-of-destiny levelling system? Including hopefully a fix to server performance issues.
Since everyone is 35+ levels at the time, without global wipe it will do nothing. Only make it harder for newcomers.
New items, everyone loves new weapons. Bannerlord has everyone drooling over Falxes, get those in cRPG I say!!!
Maybe they loves, but 80% of players use like 4-5 2-handers with like 4-5 sets of kuyaks and helmets. Rest items is barely used, only for roleplaying, like samurai etc., or trolling chars. You do think some epic gloves will do the job?
How about a new round of Strategus?
Never even tried it, can't say nothing here.
However, let's see, if it will work.
