Guild Wars 2

why is the reward for achieving 3500 ap the same as 1500?

while the reward for 2500 is significantly better.

shouldn’t you get better rewarded as you go higher up?

Think of it as an incremental reward for gaining 500 APs since the last “Large Acheivement” which is awarded for each thousand APs.

And for every 5 of those (2500APs) you get a Heavy reward.

It’s more of an incremental reward system as opposed to a cumulative one, with the benefit of potentially more desirable rewards only being offered at the higher cumulative AP.
