So I'm sure some of these things have been mentioned before, but I'll spend the next 6 hours trying to track down every little bit. Anyway, SWTOR is a great game, but it has the potential to be SO much better. Now for me, SWG was the first MMO I ever played, and by god was it addicting, the player interaction was like no other, and the feeling of being, some random dude, was great. Now I know obviously you have a questline and everyone is a "hero" but when it comes to end game, that feeling is sort of lost, now if you ever played SWG (pre NGE) you'd know that PvP was VERY unique, due to being able to frequently interact with the opposing faction (since there were no "faction zones" really) it made PvP much more interesting, since TOR features 2 uniformed and official militaries/factions, that would be unrealistic, however there were some things that could make it... much better.
So one of the BEST features SWG had to offer was faction armor, for the empire there was imperial shock/scout/storm trooper armor, now if some sort of class based armor choices, at least this would make the thing where, everyone looks the same, at least have a purpose, and the PvP armor doesn't count (besides commando) since it in no way relates to your faction, besides looking "good" or "evil" for someone like me, if I'm an imperial sniper... maybe dressing the part of an imperial trooper for pvp at least would make it a bit more... immersive? Another thing SWG had was, faction pets, regardless of your professions, if you made enough rank you could start buying faction pets (even an ATST in the long run!) this made PvP much more interesting, having these kind of options could really make a battle in the middle of tatooine feel more like a battle and less like a bunch of dudes dressed in man jams and hoodies hitting eachother with glow sticks.
On that note, a suggestion for WZs, add some, huttball, being played 5 times in 2 hours makes me want to throw my computer in the lake, and make WZs... feel like WZs, instead of 8 on 8 fighting for turrets or a ball, expand the battleground, add more players, and add more objectives than capture the turret, throw the ball and so on, one thing I thought of would be LZs to control, and while you held them you would recieve reinforcements, these reinforcements would be made up of faction based NPCs, so if I took LZ Alpha, west whatever, every 2 minutes a squad (5 or so imperial troops) would be brought in) now obviously we're not talking about the level 50 guards at outposts which require a few players and a few minutes to take down, just some basic npcs that will take a few shots to go down, this would once again... add the feeling of it being a battleground, and not a bunch of guys smacking eachother with glow sticks.
The last thing I would like to note is that most of the planets lack open world PvP, probably due to it typically being in an open field and not really having any opportunity to use realistic tactics, add some urban areas that will offer more open world pvp options, since it's either raid the enemy base or fight in the open it's too repetitive, add some abandoned towns that quests will cause enemy players to run into each other at For example Mos Eisley on SWG was a frequent PvP spot, and what made it interesting was alleyways, cover options, maybe you could allow us to get onto low rooftops, so being a sniper feels like being a sniper... these simple tweaks give players the ability to actually go around and flank your enemies, things like this will make pvp much more immersive and entertaining here it is impossible to do so since 99% of it is in wide open fields which provide very little opportunity for unseen movement (btw please reduce the distance at which you see an enemy player's name to at least around 50m or so, because seeing someone from 300m out is ridiculous.
I could go on for days about things I'd love to see implemented and I really do hope someone actually considers these things (though I highly doubt they will) and I'm sure some people would agree with me, and you'd probably up your player subs if you made pvp at least a bit different from every other MMO.
