With all due respect, the entire post is a joke. If stamina supposedly drains way too much, how on earth can you pressure anyone at all? You'd be depleted in seconds and easy to interrupt.
And career mode is not lacking in that aspect imo. You might end up losing a couple times early on, but is that a big deal? Later on - if you're good at the game - you won't notice the skill difference and you'll win all matches on "very hard" anyway. I do agree you should have more choice on who to fight, instead of there being 3 (more or less similar) choices. No, there's way more pressing issues for career.
