How do I like them? NOT overpowered or overshadowed by spellcasters, is how.
I like Fighters (and the like) to have abilities that are unique to them. Many of them. Plus, of course, they should be
miles ahead of everyone else, when it comes to "basic combat", whatever that might mean in the system in question (power, resilience, endurance, efficiency, skill, knowledge, etc., etc.)
They should also become increasingly -
literally! - superhuman as levels go up, as per AD&D (just done more interestingly, with the above taken into account, thanks). But then, that part should apply - as per AD&D - to PCs and NPCs of every class.
As for AEDU, I'm not a fan. And in particular, I don't think it works well for non-spellcasters of any kind. But if 5e uses that, I'll have a look. Perhaps it will convince me to "upgrade", where 4e failed to.
