I saw your suggestion and it still has the same problems. An attribute that gives you 75% immunity to being interrupted during a cast is silly and poorly thought out. Your arguments for this are weak as well.
If you want immunity, take Wizard 2. Otherwise, don’t. You’re asking for a passive attribute that gives you 75% immunity. I can’t even begin to explain how bad this is. For one, you don’t cast it, so you’re saving SP. Secondly this is very powerful for a rank 1 class. You can’t compare this to pain barrier. Swordsman have to be in melee range. They are in danger by attacking. Wizards have the luxury of attacking from afar. They can play with positioning. You want immunity while being able to attack from afar without any sort of investment into your build? That’s outrageous.
You should have to give up a rank for immunity. It’s a nice thing to have but by no means necessary. You’re asking for 75% immunity which is always up. It’s a silly suggestion. You haven’t thought this through at all.
Just look through this thread. Next to no one agrees and posts countering you have multiple likes. Your OP doesn’t have any likes. It’s clear that it’s not just me who is an “ignorant tool”. If so many people are against your idea, maybe you should consider the fact that your idea is not good.
