How much of a pain would it be to convert a 10 man into a 5 man, but leaving the 10man version intact as an option?
So lets use Karazhan for an option. Karazhan 10man would remain untouched and operational as normal. There would be a separate entrance for a 5man version. It would include everything exactly the same as the 10man, except the stats of the npc's would be halved for 5 people to run it.
Would this require all new database entry's or could the script be copy/pasted and somehow modify the npc's stats within the script?
