It should be noted that A5e makes exploration considerably more challenging. The conditions of a wilderness treck considerably increase the danger of "regular" combat. Unprepared and reckless players unlikely to undermine the "sturdyness" of the character
Probably the biggest change is that Crits are now a full double damage. That should make combats a little swinger. They also brought back an instant death rule, so a massive blow has a greater chance to kill someone.
