I think "Meaning" in the second line deviates from standard English grammar.
In my opinion, it should be replaced with "It means..." or "field, meaning...".
Do you agree? Or "Meaning" is just Okay?
Having advanced technology has made it so that they is no longer an even playing field. Meaning that no two players who are playing each other are equally the same because the tennis racquets/uniform are different to each other and one player’s tennis racquet might be easier to swing than the others. There are many tennis racquets which outshine others, this could be because they are lighter or they have smaller string but it would put one player at an advantage over the other which is very unfair to one player. This is actually a very common occurrence, if you went to a local competitive group and looked at their racquets, there would be some good ones and some bad ones, making the ‘playing field’ uneven.
