Overleveling

Obviously he didn't level on Ord or Coruscant. He's an Assassin.

To the original question, no. With three level 50's, one 40, and a couple of mid 30's and not liking PvP or space missions, I think XP doesn't come quickly enough. I have fun on my main, I want to finish the stories on the other classes without having to grind XP through repeating content again and again and again.

Repeating things like that is for dailies/weeklies and Ops

Unless he has done nothing but PvP and space missions for the last several levels.

Yes totally. It should be possible to get to level 50 in no more than a couple of weeks. That way we can all get bored within our free month and quit for the next MMO without ever having to pay any subscription fees.

That seems to be their business plan actually.

Some people want to skip as much quests as possible because they are leveling 4th alt and already done them all many times. Yet some people (like me, who just rolled 1st Republic character) want to do them all and still stay in their level range.
Is there a solution which will suit all these people? It seems there is! Just make diminishing returns on XP from quests/mobs that are below the character's level much stronger. For example: on-level quests/mobs give 100% xp quests 1 level below character give 75% ... and those 4 or more levels lower give no XP at all.
My current "solution" is to skip all solo quests except class story, and do heroics/flashpoints only once. This way i stay 3-4 levels below content, which gives some challenge to class quests
Also it would be nice to remove the god mode for players that are 9 levels or higher than mobs. This is what prevents me (and many others) from grouping with high-level players. Mob's base miss chance vs lvl50 character should be the same as vs on-level character.

I have always thought it should be the other way. Doesn't matter if the NPC is 10 levels higher you should still be able to hit it, you just won't do much damage. Too many resists and misses based on an arbitrary level slows down those leveling alts and forces them to do planet quests/pvp/space instead of challenging themselves for fun.

And flashpoints. I'm doing everything at level, meaning whenever a new Space Mission or Flashpoint shows up, I leave the current planet I'm on and go do them, once I've done them, I return back to that planet. Hence the reason I am in my 30s and still haven't finished Nar Shaddaa.

Remember if you play on a High pop server, PvP queues after the first one are usually instant. I've done a Warzone, and literally had the timer for the second one count down to 10 before I finished loading. There are times I get 5 or so warzones in before I complete 1 quest.

You see, the purpose of MMO developer is to slow your progression through the game. Otherwise you will bring some friends, complete your class story at lvl30 and quit out of boredom.
For example, i once tried Morrowind. It went like this:
1) Spent 1 hour in the first encountered shop buying stuff from vendor and selling it back. When i maxed my trading skill, i could sell stuff for more than I spent to buy it. This way i made quite a lot of money.
2) In the first town i went to the magic shop and bough a custom spell: big fireball which did a lot of damage in an area and used all my mana.
3) I filled all my inventory with mana potions
4) Spent next 2 hours trying to find a mob which would not die from 1 fireball. Finally found some demon, who required 2 fireballs
5) Got bored and uninstalled the game.
MMO developers certainly don't wont anything like this!

Because the only reason you are playing an mmorpg is for the level grinding?

Everyone knows that the only reason to play an mmorpg is so that you can race to level cap to farm lowbies in open world pvp.
