Prohibit class/job changes inside dungeons

[Jinko]

Just remove speed runs they are kind of pointless anyway, of course this won't stop class stacking people will still go after the faster way to clear a dungeon.

There are several things they can do:-

1:- What the OP suggests, lock a player to the class they enter the instance as (this would actual be useful for the Job Quests also, seeing as people managed a way around that)

2:- Give each class an aura, meaning a more varied party make up will ensure better party buffs. (this would probably require removing strength in numbers and comradery) - Aura's can not stack from two of the same class.

3:- Remove strength in number and comradery if 3 or more of one class type is detected.
