Why the lack of underwater content?

The only good thing about Vash'jir is that it's low enough level I could stay in Northrend a little longer and just skip it. Took a little longer that way, but much less pain and suffering.

I had a boatload of alts, some of which were still stuck at 70 with just the regular flying mount (since i spend all their money on my mains). Instead of leveling in Hyjal with the slow flying mount i leveled in Vashjr which had the 450% seahorse mount. hehe

Well, we saw underwater combat in The Clone Wars (worst story arc ever, but still...) and Clone Wars. Lighsabers and blaster are working underwater in Star Wars, so there should be no problem with that.

Manaan? Yes, pleas! And it's true that they don't have to put much effort in making that kind of planet, also we don't have anything similar to Manaan or Kamino in SWTOR so it should work. But I don't think there should be much content underwater, maybe something related to exploring and using this droid, but nothing more.

I did Vash'jir once with my Hunter, which wasn't so bad. My Paladin would have done it next, but I knew I'd have just hated it with a melee character.

Aye, do you do anything other than complain on these forums?

I can't believe some of the things I'm reading here. "Everyone hates underwater content", are you people for real?
That's like saying everyone hates racing games, or platforming, or whatever other feature/genre you can think of.
Some racing games suck, others are fantastic. Same applies to the platforming aspects of a game; it's all in the execution. Just because you didn't like GW2's underwater aspect—which, personally, I quite enjoyed—doesn't mean you wouldn't like a similar feature in SWTOR, provided its design was ingenious enough to cater to your personal tastes.

But anyway, onto the point: SWTOR was obviously released in a germinative state, as most of you know. However, its developers were smart enough to leave a foundation in place that could allow them to add certain elements—or rather, systems—to the game post-release. These can be found all over the place (I'm surprised more players haven't picked up on them), and include systems as potentially complex as vehicle hit points, weather cycles, counter-spying missions (Last Emperor Flashpoint), pazaak, swoop races, entertainment careers, player housing and yes, water-based shenanigans.

"But wait, what are you talking about? I've never seen anything in the game that suggests the potential inclusion of any water-based systems! Troll."

Well then, you aren't looking hard enough. Why don't you go ahead and go back to Ord Mantell. Do the class-quests there with either a Smuggler or a Trooper and count the number of times NPCs expressly state, loud and clear, the necessity of your having to swim across to Manett Point because the bridge is out. There's even a reference to the use of a hydro-speeder on the Trooper side. But then, when you get there, the water barely goes above knee length.

This vast body of water NPCs keep alluding to was obviously not meant to remain in its current puddle-like state indefinitely, and the reason why it was put in place in the first place was so that it might allow for the future inclusion of swimming/hydrospeeder features. This is why I keep going on about retroactive changes, it's essential that they preserve the original creators' vision: mostly because it seemed a heck of a lot cooler than anything we've gotten thus far.

I hate water content. However, I do find it strange that I can Jesus my way across any body of water. Slightly immersion breaking....just feels half assed from a development standpoint

Would be cool if there was an underwater base or city, like in KOTOR, with maybe a mission or two that requires you to go outside the base in an atmospheric diving suit. The next planet is going to be Naboo, so fingers crossed!

Im playing from underwater right now and see plenty of content

well Im not big on underwater content either and the KOTOR1 underwater animation was horrible. Plus those damn shark things scared the bejeezuz outa me!

Though others have made logical suppositions as to why - the game mechanics, the animation, etc
