The above is an historic screenshot because it shows what had happened to the game by the time I returned to WoW, which was during patch 4.2:Rage of the Firelands. I had originally quit in late WOTLK.
I returned to WoW only to find my guild had switched to 10-man instead of 25 man, 80% of my guildies had quit the game, 75% of the people on my friends list gone, and my server had become a ghost server.
My WOTLK guild, which had been together since Vanilla (2006) as a Dutch guild does not exist, and EVERY SINGLE ONE of my friends has quit. They didn't even try MoP. Like we have explained to Blizzard several times, this was the result of:
1. Blizzard allowing 25 man raiding to die (many people quit as their DPS role no longer fit in 10 man guilds or they didn't like the 10 man model and couldn't find a 25 man guild to raid, and 25 man guilds were the glue that held the community together).
2. Several other flaws in both CATA and MoP.
To sum up, the game has changed way too much since the original (Vanila, TBC) in fact so much so that it is no longer recognisable as the WoW we fell in love with.
