Is it the PvP in DAoC that makes it feel better? The different realms? The customizability of character builds?
The reason I ask is that, to me, DAoC feels more restrictive. You need a healer per group and a tank per group and a mezzer per group and probably speed too (although some of those can run together in some realms), which to me seems to offer less variety in how groups can play.
Now, if you’re soloing I think the characteristic experience for fighting is a lot more similar in CoH than DAoC, because there are about 6 different class archetypes in DAoC (Pet class, beating tank, casting light tank, healer, damage caster, trick/utility caster) vs. CoH’s 5. But I have trouble looking at these games from the soloing viewpoint since, frankly, I’ve yet to find one where soloing isn’t always the least palatable option.
(The depth statement really caught me because people always hold up EQ as a bastion of depth, when to me EQ is about as linear as it gets, and just has a long, long, long linear path to go down due to all the content addition at this point. Then again, I’m tempted to call “depth” the ability to do radically different things, making SWG the winner in my mind simply because of the fact you can go all the way from a combat drone to a competitive dancer.)
