Anime where MC has to put in effort to get strong, and fights are more realistic.

Just got back into anime a little while ago, and I'm already tired of all the shows where the MC fights against highly skilled and experienced enemies by just swinging a sword randomly.
It's so irritating, like, here's this super experienced soldier and the rookie MC fighting each other. MC is getting beaten around like a sack of straw at first, as is expected, but then a baddie stabs his friend, or his crush cheers him on, and then BOOM, his enemy completely loses the ability to dodge as the MCs friendship powered attack slowly comes towards him and hits him, completely 1HKOing him.

Talk about anticlimactic?!??! Perhaps I'm a very, very, VERY tiny minority but still, wtf. Might just have to stick with the 'cute girls doing cute things' genre. :P

If anyone knows of any animes where the there's training, failure, and intricate battles I'd really appreciate a recommendation. I've really been in the mood for some quality animated fights. Also, the use of 'techniques' is also a huge plus.
