I get it... and it may sound harsh to the tender ears around here, but I have zero compassion for someone complaining about the free experience. It's free. No matter how much you may spend aside from it.... it's not a subscription-based activity, and ANYONE paying a sub and acting within that subscription's allowance has every right to infringe on what you
WANT your free experience to be. However and whenever Blizz swings the pay2play experience in that direction. F2play has always been a TRIAL-BASED scenario meant to allow people to try out the game in hopes of getting some subs. Yes, they expanded it and gave the appearance of a free-standing experience but it still is subject to change without cause or apology however that intention is deemed to benefit that goal.
So TL;DR.... tough titties, kids. Sorry your non-subscription activity isnt everything you demand it to be at the moment.
