I agree 100% on the upgrades of kill streak achievements and the lottery system achievements.
Even if we used the logic of.. 500 kill streak would grant a lot of rewards along the way to the 500 kill streak.
If we used that logic then the ::vote reward achievements needs to be SUPER nerfed. For voting 1,500 times that would be 1500 vote tickets + 1500 vote packages = 3M PK points if sold for 1K each. However I am still rewarded 127K PK points for voting 1500 times. I already got 3M from voting 1500 times.
