As far as grind and being time consuming goes, I hope Bioware play it smart.
What sucks more than anything else in MMOs have to be waiting around for groups. IMO, this happens due to poor LFG-Tools, poor chat channels and poor social hubs. It's against the point of the game, for people to be handicapped in effectively fighting other players to play with.
Blizzard made the mistake of not having good tools implanted at launch. This created vast lasting effects that would be felt throughout the games life. As Blizz, later wanted to improve the LFG-experience, it was already to late.
What happens is that people become creatures of habit very quickly, and thus they won't willingly change something if they don't have to. It's why things like Meeting Stones, and their other LFG-tools, never really worked that well. They had to be implanted at launch, so they habit of doing an effective thing for getting a group would get planted in the players, early.
Bioware have said that gear will only counter for 10% of the power between players. This is very good. This is smart. The less they run on peoples vanity and time investment > skill, the better. Greed and consumer mania inside games make people even more jackasses.
To make an meaningful end game, we can only hope the world pvp will be amazing, but I have my doubts if it will really be significant. They really should go all out, and make a CAPITAL F**KING LETTER WARNING; STATING THAT YOU WILL GET YOUR FACE PIRCED BY A LIGHTSABER CHAINSAWS EVERY DAY.. EVEN DURING YOUR HOLIDAY ON DANTOOINE!!
It's important for the community too. Two operations and a some over-and-over-again-Battlegrounds is okay, but I don't think it will be what makes people tied to the game. For the first many hundreds of hours it will be single player-like story, and that's fine, but I hope there will be a real sense of guildmanship.
A real reason to be in a guild. In WoW you dont need a guild unless you want to raid. your just there for the benefits. the game has so many gang-up-prevention tools, that you dont get that lets-band-together-so-we-dont-get-fucked-over-by-scary-men-with-lightsaber-dildos-with-frills!
Eventually I think it's the fault of the themepark model as a whole. It's fun exploring, but once you have seen it and done the the quests and gotten the resources, you don't need that gaming space anymore. its just some empty land mass for the next guy who rerolls a class that has to go through that area.
I don't think this is very intelligent design. You don't fight for the territory, you don't mix it up, it does not change - the time of day doesn't even change.. ever.
And in space were they could easily make contested territory, since it's just some space.. you don't even have to render the ground since it's just like one big 360 degree angled skybox. guild capital ships, getting crucial resources for your side.. sending ships out to mine minerals, and thus getting a bigger significant advantage in the war.
Look no further than real world history for inspiration. In World War 2, the germans where triple f**ked from the start because they only had 10% of the worlds oil reserves while the allies had 90%. This was bad, and hindered the germans in a lot of ways.
it's that sort of omg-dynamicness that make the game feel alive and will make guilds seem important. even if your not a social type person, I truly believe that when you think about this game 10 years from now, you wont remember shit about the lootdrop you had that one time, or that cool quest - but you will remember the social interactions with cool people... that's at least what I think about, when I think back to MMOs around 10 years ago. smeh.
