Idea for a block meter rework

So a lot of people hate the block meter, but I, as well as many other players, also recognize it as being a creative and original mechanic that really adds to the game. People of proposed ideas that remove RNG but those don't float with me well, as I feel that for balancing it NEEDS to be random, so if you play a mayflower you have to think whether a pea pod will pop the block or guarantee the mayflower gets blocked, and of course you never know 100%. You need to be prepared for both outcomes. So my idea is to keep the RNG, just make a very slight change to avoid totally stupid results were one player gets amazing charges throughout the game and the other player's doesn't. (disclaimer, someone may have come up with this before, but if they have I haven't seen it.) Over the course of a game (assuming you block three times) you will get exactly 5 triple charges, 5 double charges, and 5 single charges. Note that this wouldn't effect odds of getting charges unless you run out of a certain level. E.G. you need 2 bars to fill your block meter, while you will never get a triple charge you still have a 2/3 chance of a double charge. However if you already had 5 triple charges you would have a 1/2 chance. Anyway, that was just a little idea i had. The main drawback that occurs to me is that it would be pretty hard to keep track of who used how many charges, if that was something you wanted to keep track of. Maybe if they implemented a super-expert mode or something.
