I'm sure it would be fun for the average Joe to be able to use items and long cooldown spells in rated battlegrounds, but as far as I see it, the average Joe can just queue for regular battlegrounds if those mean that much to him that this is a dealbreaker.
How different is the Arathi Basin experience in a rated battleground match as opposed to a non-rated one, really, besides there being a ranking and winning Conquest points instead of Honor ones?
The reasonsing behind those restrictions for competitive play is sound.
You would have to pick up engineering for rated battlegrounds so you could use the likes of bombs.
This would be mandatory.
You would be able to use items that were never meant to be used in such a context as well to impact the outcome of battle in ways Blizzard cannot even imagine at the moment.
Needless to say, how many potions would be used every single game? To remain competitive, a player would have to use more potions in a week for rated battlegrounds than any raider would use in a year.
Speaking of potions, the likes of Free Action Potion and Swiftness Potion would run rampant.
Nobody abuses those in regular battlegrounds, because it just doesn't matter that much...
But it a competitive environment, it would turn ugly, fast.
They've restricted you to use either elixirs or flasks. They made flasks last a long time, and cost practicaly as much as a regular potion. They've restricted the need to always bring out food by making a particular food item that could give Well Fed to the entire raid...
Let's take a raider, out of the blue:

This guy has only played since WotLK.
How do I know? It's a death knight...
He qualifies as a serious raider.
How do I know? He killed Heroic Lich King 21 times.
So counting raiding, dungeons, leveling up, and any other time that guy has played, he's used a grand total 106 Runic Healing Potions.
That's 100 potions in 2 years.
Allow potions to be used in Rated BG. You'll use 100 potions in a week.
Your argument has no basis in reality when comparing the frequency of usage of potions in competitive PvP and competitive PvE.
Needless to say...
Would giving everyone a Free Will Potion ability on a CD along with a health potion ability add that much depth to the game? No...
