Hello!
I would like to share my experience about pvp. I decided to play with a smuggler, as a healer. I'm only lvl 14, so many more content is ahead, but still, there are some things that struck me when I went to warzones.
First of all, there is still the annoying lag, not that much as we saw in the beta but still, it is there and still annoying.
Secondly the heal/operation UI iss till not working properly sometimes. What I mean, is that it often does not display actual hp values properly, also the UI sometimes forget to display those who are in range. This problem also occurs in flashpoints and heroic group quests.
Thirdly, In Voidstar and Hutball when people die, they resurrect in their graveyard, and they often have to wait a lot of time before they are allowed back in the fight, and several times we won and lost because of this awful lot of wait time. It is not fair to either side, because the players are forced to watch how they lose, because the graveyard lockout forces them into spectator mode.
Lastly, and this is my own personal feeling: There is too much cc in the game, or at least the cc protection is not as strong enough. what I mean is that when you do pvp, you cannot cast nothing except instants, due to the various aoe, knockback cc, and aoe pushback (jet boost and such). It is near impossible use anything with a cast time. The problem does not lie in the above mention cc effects, but in the fact that it seems there no line drawn to limit these effects, but if there is, it is so loose, that by the time the protection kicks in, you are probably dead already 90% of the time.
