but there is no action gaming in a mud
You're saying you never experienced a wall of text assault you and having to shoot out commands like bullets out of an automatic rifle.
Imagine a round length of 1.5 seconds.
Let's say you get attacked by 3 participants. A rogue trips and stabs you, a warrior bashes you, a mage casts hold person on you. You have less than 1.5 seconds to react THIS round or you'll get hit with more stuff the next round.
You manage to pray to gods for a one in 15 minutes dispell of all negative effects, get up, run north - 3 commands in the span of 1.5 seconds. Okay, great, now that's only the beginning, because as soon as you do, they follow you into the room and assault you with more abilities and spells. You can try to use your next 1.5 seconds to disable one of them and then continue running away. That requires extremely quick thinking and crazy typing skills.
"No action in muds"...
How is EQ decline? And have you even played it?
I won't pretend - I only played EQ2. It had less to offer than Muds and UO, it was casul-friendly and people mostly played the "game around the game" - had romances between players, websites dedicated to their guilds, their characters had stories, etc. This was the charm of the early internet. Take it away, and gameplay-wise it's a step-back from older games. The very definition of decline. EQ was like an early beta of EQ2 before being augmented with more mechanics. EQ2 was a Pre-LA2. And LA2 was an almost-WoW. And WoW was a turd in a candy wrapping.
