Multiple Actions House Rule

I've found that the multiple actions rule is a bit cumbersome.  I found a house rule that makes a bit of sense at least for me.

If someone wants to make multiple actions, they take a penalty to all dice pools equal the total number of actions being taken. (E.g Stu the Nosferatu wants to take three actions this round without the use of Celerity. Stu would take a 3 dice penalty to all rolls taken that round. If Stu had Celerity, his dice pool would refresh at the beginning of his first Celerity action.) As per the rules a character may NOT split any of their Celerity actions, only their first.
