After farming over 100 M+ 15-19 Keys, YMMV- but the time spent vs rewards earned are questionable.

Proof:http://ift.tt/2vYmLfU know most people who do these things besides just getting a +15 done for the week are there to do it for the challenge. But besides competing for spots on a 3rd party site leaderboard- there is no real incentive in doing them. Even when I hit world 100 for my class 2 weeks ago, no one cared and there was nothing prestigious about it and the time spent could have been doing other things.After all those runs I have gotten exactly 4 item level upgrades.930 relic- up front 915 heroic relic from heroic raid (BIG)925 boots- up from 920 heroic warforged from raid (MINOR)925 bracers- up from 915 heroic from raid (MEDIUM)925 belt- up from 920 heroic warforged from raid (MINOR)So in conclusion, for those who are chain running M+ 15s for chance of farming Titanforged gear outside of raid. Out of about 101 runs total I only got 4 items worth of upgrades over what I already had from heroic ToS. Obviously, some have had better luck than me- but let this individual data decide for you whether farming M+ is worth your time and effort.
