Wilhelm could wipe out the ML temple in less than 30 seconds, and he's not even a good build for PvP. Radu would take even less time than that.
The reason monsters don't go in and kill the healer is, one, they're not allowed to unless a DM is present, and two, they have more courtesy to their fellow players than that. Since there are a good number of players that refuse to show that same courtesy back on their own, since they know nothing will ever happen to their characters for doing these things, I think it's a valid suggestion.
Sorry for the harsh tone earlier. Shooting from the hip at 3:30AM is never a good idea.
I never said someone should go into the temple and kill the healer. What I meant was taking the fight to the person who ran into the temple. That may be disrepectful, but I wasn't aware a werewolf or wererat was that discerning. That, I believe, is not against the rules. And not very smart.
But, honestly, you answered your own question here:
The DM and Dev team may not see it that way, but the majority of the people posting in this thread seem to.
Until they do, there will not be any changes and the reason for that is they see the big picture. Usually, not always, these suggestion threads are a result of something that happened ingame. Something happened to somebody and they didn't like it. So they want the game changed in some way. And the player community gets riled up. Then it dies down, until someone else brings up.
We've had this discussion before and I believe it was determined that leaving a fight, running back into the temple to rest or be healed, and then running out to fight again is NOT transition abuse or an exploit. It is a legitimate tactic.
The monster PC should also use the opportunity to rest or heal or just run away. The point was made. The monster PC got their fight. It's time to move on instead of facing a stronger enemy who may have just found a few friends inside who are also spoiling for a fight. Or stand and wait and face the consequences.
I understand it must be very frustrating to be a monster PC and find out you (generic you) are not all powerful or you've given up so much for the template. Some don't last very long because they take chances like attacking in a crowded area with 2 rest zone.
Others seem to be around forever, like Yves Zun, because they don't take chances. They pick their spot carefully with an eye to escape and not just "the show". Their reputation goes on while other monster PC's are long buried. There's a reason why Yves Zun has lasted. They play smart.
Bottom line, I really wish suggestions would be made directly to the developers. The decision will be made there and not here.
