Fighters are often talked about as being the easiest class to use, and champions are the easiest version. It’s so mechanically simple that it’s the default subclass used on the main class handbook, and even with no feats it does a pretty decent job of maintaining reasonable DPR. With that said, it is entirely still optimizable, and, with a combination of feats and tactics, can turn into something capable of being an incredibly durable Striker capable of carrying the party back from the brink of failure. It’s sort of built around being the Fighteriest Fighter with an extra fighting style and the passive ability to crit more often, and we can take both of those and thoroughly use them to our advantage. Our Elven flavored advantage, if you follow the example build.
