Ultimately it all falls on whether you want to or not. I quit multiple times in the past and recently my recent quits or breaks if you will, were more voluntary. I remember those days when I used to get screamed at for playing in into the wee mornings. Nowadays I still stay up in the wee mornings as old habits die hard, but it isn't wow related anymore. Back then when I was addicted and paying for the game, quitting was simply a means to try to tone down the amount of playing.
I still remember vividly playing 19 twinks on my CRT monitor at my old house just having a glorious time in wsg. However, of course we all know that 19 twinks are pretty much a dead bracket now (I played when exp off was the norm). The games were still considered fair, but each side had their same share of twinks.
The 20-24 twink exp off bracket has a lot to be desired. gone are the days the 24s are a rarity. I see on average 4-5 24s per game. Worse is when the 24s group together. Not to bash the activity of premades, but for the other side, it simply ceases to be fun at that point (for the opposing force). Until everyone accepts all out F2P or all out 24 P2P, the bracket will soon skew towards the 24 side, along with many f2p joining their servers or joining the side that has the most 24s(horde). F2Ps will have an existential crisis and will resort to more FOTM model approach as they need as much advantage as they can logically speaking. Then through sheer exhaustion of facing myriads of 24s, quit the f2p game and more than likely the entire game as well and leaving with a bitter taste in their mouth.
As for me, this is why I am quitting. The free game version ceases to be fun for me. I still log on time to time to see if other f2ps are on, but as each day goes by, less and less of them are prevalent. Your experiences may differ from mine, but the direction this bracket is going is clearly straight down.
