I have an execution/annex/guardian account. Ranked under 100k in annex, 400k in guardian and not sure about execution. Though the kdr is very nice (never used a modded controller, fully legit) I can provide more details if you are interested.
Edit: Just checked. I have 1.2m experience in execution with a 2.1 KR. If you'd like the KR along with exact stats of any of annex/guardian/execution just contact me =)
