Warning: Long rant on why no one here is right or wrong yet, and a few notes to back up ShonaSeraph, the only one other then the OP that seems to have a realistic view of what we do and do not know already (hence the question, or implied questioning anyways from the OP). And those saying that one has the option not to play at all, well... seriously, either give a positive opinion or do not post. The OP wants answers and speculations, not someone trying to set them up for failure before anyone sees SE's true intent in this game.
SE has commented months ago that you can either be the best in one class, or efficient in many. Who knows, if the OP wants to play straight Lancer all the way to the end without leveling anything else, there may be a chance that even though he may not have sweet abilities from other classes, he may still be uber in the fact he is pure Lancer. Who knows at this point, even if he passes up solid dps skills from other classes, he could still be strong for not varying away... perhaps there may be a chance straight, unwavering play style of one class may be stronger in endgame due to some mathematical equations since time and physical lvl versus weapon skill aren't distributed in another class (I actually assume there will be some equations put out there on just about day one as to the economics of 1 "class" vs hybridizing a character; I personally plan on 2 characters just to keep my DoW classes and crafter/experimental classes economically aligned in terms of physical lvl vs. skill lvls)
I could be totally wrong, but on the same note, from what I've read, even the experience points distribution is yet to be finalized in beta and most likely still being worked on in terms of balance. In all fairness, for example, physical lvl of say 50 with lancer skill of 50 (or however each is capped) may be more appealing then physical lvl of 50, Lancer of 30, Marauder 20, Conjurer 15, etc, etc; but then again, maybe not. We are yet to know lvl caps and endgame balance. We are yet to know if pure Pug can tank as well as Glad and what situations determine what or if mostly Pug, part Marauder part Therm is better then pure Glad, or even if it matters as long as that form of tanks abilities are maxed and you "need" other abilities. What I am actually hoping is that skill, as in players knowledge of his class and actual individual style of play is the most important factor in game, followed by gear and the other factors.
I played WoW for 2 years (and dabbled in Aion) after 5 years of FFXI and I'm sick of cookie-cutter builds as well as elitists that use other elitists stats, experimentation and numbers without trying anything on their own, that's not being an elitist, that's being a follower... "I have the best equipment and rotation because this site said so, and you are wrong because that hasn't been tested out, or has been useless since patch...." I mean seriously, I took an Ele Shaman with endgame gear from 10 man Ulduar and turned him into a beast (as in top 5 in dps, with a few times topping the charts) and took down 25 man ICC, just following the "best" gear setups and talent build put out by testing by an elitist, and it only took about a month and a half with my guild to go from sub par to the top. Ended that subscription fast after realizing the BS (I am far from an elitist, why is this too easy, where the fun?), especially because it was mindless, uncreative at that point. I rather have earned Homam and made it last for years as opposed to hard earned "uber" and BIS drops becoming obsolete every few months. If you want min/maxing at its best (or worst), Cataclysm should be coming out soon.
You all get what I mean. Give the OP and everyone else a chance to play their style, because ****, it will take a little while of number crunching and actual endgame experience to see how flexible and unwavering SE's definition of freedom is. Who knows, maybe a pure Lancer will out perform any combo DD class given same skill lvl or physical lvl in the end, or maybe the numbers will round out to be even regardless of abilities from whatever classes are spammed, and this thread is 100% useless.
* Edit When I started writing this post, ShonaSeraph was the only one to post with a head on their shoulders, since then, others have stated intelligent facts/speculations about the game as well. In no means do I mean to refute or belittle anyone's intelligence or intentions, as long as they are factually based or positive and helpful.
