Is there a meta in Halo 5? Should it have one?

I am currently thinking that a lot of games, if not all of them, have some meta aspect and I wondering if this aspect extends to Halo 5 as well. I know that right now Warzone Assault has the second base exploit, which does fall into the category of metagaming. Aside from that though, I don’t think Halo 5 has any other ‘strategies’ or exploits like that.

Another thing is that if you consider these meta things good or bad. I personally don’t really have an opinion and believe most games have some kind of metagaming aspect these days. Something else to note is that most games like this tend to be a lot more popular and considered to be more skill based by many. I will name some below.

Some metagaming examples I can think of from the past:
Halo 2’s and some its exploits
Star Craft and Star Craft 2’s online playstyle
Most RPG, strategy, and real-time games.
Card games like Yu-Gi-Oh and Magic.

I am bringing this up just because I was curious, nothing more. I am not advocating one thing over another. Please no hate.
