How I would have improved Paige
So we all know that Paige was too much whitelighter and not enough witch. Here's how I would have changed her powers and what I would have kept:
Kept: Telekinetic orbing Albeit, I would have made it a solitary concept like it originally was only pertaining to her. I would have made it a bit more stationary though, like objects orbing in the swirl of white lights not like the whitelighter lights but like the witch lights used for teleportation.
Ditched: TK Orbing being Overused When it came to Wyatt and just about every other whitelighter, orbing became overused in the later seasons.
Kept/Introduced: Sensing/Empathy Whitelighters are intuitive, and so are witches to some extent. Paige is no exception. I would have chosen Paige as the sister to get empathy as her secondary power instead of just being a whitelighter who could cast spells and make potions.
Ditched: Over Excessive Acknowledgement of her whitelighter side She would still be half and half, but I would have made her powers more witchy. In early episodes of Season 4, such as the episode Size Matters, shows just how much her intuition guides her. This goes back to the sensing and empathy mentioned earlier. I would have ditched the excessive reliance on her whitelighter side and made it much more subtle power-wise.
