You should preface your opinion with "I am a big GW2 fan and take my opinion with a grain of salt". There is no objective data that you could toss out to confirm your wild belief that GW2 had a good leveling system or a superior action combat system. In fact that goes against the grain quite heavily.
You are also underinformed about Wildstar. Attempting to characterize leveling up as 'wow like quest hubs, oh u can pvp I guess" shows either a lack of research or intentional downplay. In addition to traditional quest hubs interwoven with path content you have both dungeons and adventures. Dungeons are somewhat traditional with significantly harder tuning and of course a balance between trinity for team dynamics and a higher burden on individual players with more position requirements/harder interrupt mechanics.
Wildstar also has adventures which are branching scenarios similar to dungeons in concept but with more of am emphasis on recreating epic quest scenarios with group decision making. The combination of adventures, dungeons, overworld questing/paths/rare monsters and pvp is just a more fluid leveling experience than both GW2 and TSW.
Combine these detailed content plans, a game that was designed top down (Endgame already exists...GW2? Where was your endgame), and a combat system that hybridizes traditional hotkey mmo teamplay with more mobile/action elements and very lol-like skillshots meshes so well together.
I see nothing but emotion in your statement. Factually you could say "The Secret World has a more intricate story, compelling puzzles, deep characters, and the best mmo environments ever made", you could say "GW2 is a fun couple week leveling experience and has a lot of dynamic content for alt lovers" or "Swtor took a formulaic model and added a fun, engaging if a bit repetitive story structure while having all the bells and whistles that make it a solid, playable longterm game".
You should have prefaced your response as "Fanboy to the rescue!". Though anyone reading your post, and its subsequent rants could tell that easily enough.
I wasn't bashing WildStar at all, nothing in my post was wrong in its description of WildStar, nor was I trying to sell GW2 as being a better game...that was just coming from your own prejudice against GW2 (a game which you seem to hate).
Leveling in WS is mostly questing via hubs in various areas, surprisingly similar to WoW, with dungeons (like WoW), and the ability to forgo questing / dungeons totally by leveling up via PvP. The Adventures (Story ones) you can run at 35+ sound great, much more developed than the later stages of GW2's Story quests. A big plus for WS are the Shiphand missions, and I hope there are more than 3-4 throughout the leveling experience.
Combat? It is nearly identical to GW2 in mechanics, except WildStar added in its telegraphs, which are overdone (imo). Both allow movement while attacking (though WS has stationary attacks, and GW2 has animation cycles); Both have a dodge mechanic, amazingly the default for both is 2 dodges before depleting that resource; GW2 is a bit less freeform than WS, but I like both styles (less than than the other games I mentioned though). It is a matter of preference.
Anyway, I plan on playing WS with GAF, just as I've played GW2 with GAF (a fantastic community, btw), and I hope to have as much fun in WS as I've had/have in GW2. Hopefully your fanboy-ism doesn't throw you into nerdrage as much as it has in this thread. Carry on!
