Spell interruption - Why does it exist and will it be removed?

[Lienn]

It's important to say...interruption rate now is nearly 100% if you get hit from behind. It has been annoying the hell out of me. ><

IMO it must exist...after all you have to conjure a spell...so if you get punched in the belly and happens to scream something outside the spell, like an "Ouch!", it is expected to break the conjuring.

I'm not sure if DeadRiser was being sarcastic or not, but yes...it's immersion.
