You mean unlike DDO where everything is about... DPS?
I have to tell you based on my experience, the Other Game has a way more tactical feel in it when you do need to group. The difference is that most of The Other Game is intended to be solod, and that aspect of it is very, very rinse/repeat. DDO... these days its DPS DPS DPS. That's why AC toons are so rare and unloved in groups outside raid bosses, its why any class balance complaints you see are all about damage output, not tactical usefulness or survivability etc etc etc.
The only exception I can think of is healing, and the ability to do traps. The first is vital for the DPS DPS DPS method to work, and the second is vital in elite/epic content. Below that you can avoid almost every trap with little to no risk on every class (I agree by the way that a rogue splash should never be as good as a mechanic. I would love to see some traps in the game that only a mechanic could have a reliable chance at overcoming).
I'm talking gross generalisations here of course. I personally love all those PrEs and tactics that are shunned by the 'majority' (by which I mean loudest) of forumites - I love my arcane archer. I'm loving my lowbie AC toon very much indeed, and I'm going to miss my Earth Savant sorc so much when I TR to arti I think I might actually shed a tear (but those crafting bonuses to my crafting toon and Evocation bonus PL feats are too good to pass up).
But what PuG groups want is damage output. What 'top' guilds want is damage output. The overwhelming majority of opinion on the forums is that damage output is more or less the only thing that matters, with the hitpoints to absorb a failure to think of doing anything other than damage a close second.
DDO is capable of so many more ways to play. But none of them are as fast as 'kill it quickly', so that's all anyone wants to do. Its depressing really.
Anyway. That's so far off topic as to be unfunny.
Artificers being unavailable to VIPs 'free' through in game means (either just available or via favour) at launch is wrong and unfair, and I hope they do something about it.
