Just because you dont like the way it is doesnt mean that its working wrong. They meant to make it so 25s could beat 30s if they had good enough guns. If you had a maxed gun, youd be able to take out 25s easy, as long as you stop missing. I mean, you got him with maybe one round of the fusion rifle and took out all of his shield, how much more of an advantage do you need?
What are you expecting man, if youre not good, youre not good.
