I've been a sub since launch and this has caused me to finally unsub.
I wasn't onboard with the new GC system in the first place and as soon as I find an upside to it they slashed and burned it. I'm a filthy casual who doesn't have a lot of time to grind and BioWare's response to this is just mind boggling. Whether intentional or not they actually gave us a reason to finally stop skipping all non quest mobs. It's like they don't understand their players at all, some people may spend hours grinding these mobs like it's their job but that's probably only a fraction of the player base and instead of doing something less intrusive like just lowering the weekly cap which would only impact those grinding their asses off (more power to them) they cut the kill CXP which likely affects players like me who only can only play a single digit hours a week most of the time more than those who can spend all day grinding
Maybe I'll check back next expansion
