Unless you spend points on initiative while leveling, there is no way you will have somebody in heavy armor and weapons with 80 initiative. 50 or 60 more likely. And that will nosedive with few sweeps with the great sword. And spending points on initiative just to get dodge bonus is a very bad idea, cos you get 1 point of defense for about 7 points of initiative. That’s 1 point of defense worth 2 full levels. Point which gets evaporated after few rounds of combat anyway.
