I can see that the server is going to promote active gameplay and less mulestory (lol) BS are mostly used as a mule or leech farmers. Given that they are pretty much static/useless in boss runs (mainly KREX, Zak/ except HT), giving them the ability to disable cancel WA/MA would push more bishops to be accepted into runs and push for active playing. That's definitely going to reward already active BS and invite more active BS players. Mainly, Im talking about Zakum or Krex runs. To avoid this skill to nullify crash of paladins, yall can just adjust the percentage however u fit to balance it. 5% seems good to me tho (20 dispels to disable cancel wa/ma of boss). Feel free to comment your thoughts on this, especially BS mains and peeps who run bosses frequently.
I think this isn't going to fix any of the mule story problem. One can still bring BS mule, and control it only when WA block is up. The main atk has nothing to do when WA block is up anyways. This is just going to end up like the pala crash role. Going in as a mule, except you spam it more times before it works.
The best solution to stop mule meta is taking off safe spots for mules at bosses, this would just take away the pally spot in a party since most people muling bish can control both attacker and bish decently, also as said above: when w.c is up you don't have anything to do on your attacker, you could just switch and spam dispel.
Eh, not really a fan of this suggestion. Even if it were implemented, it doesn't really change or impact the problem that you're outlining, no matter what % chance you give it. Dispel is quite an amazing tool for bosses with defense buff (HT, Dunas1). If a change like this is implemented, I would just bring my bishop to krex/zak with my attacker and spam dispel without having to even move (exactly how one does in Dunas 1), or just bring a pally friend (which I prefer more.) I guess I'm making the same point as @kisuza , but just giving a precedent.
